Reading from the Book of Exodus
15The Lord said to Moses, «Why are you crying out to me? Tell the children of Israel to move forward.
1Then Moses and the children of Israel sang this song to the Lord, they said: I will sing to the Lord, for he has triumphed gloriously: he has howled horse and rider into the sea.
In those days the Lord said to Moses, «Why are you crying out to me? Tell the Israelites to move forward. You, lift up your staff and stretch out your arm over the sea to divide it in two, so that the Israelites may go through the sea on dry ground. And I will cause the Egyptians to stubbornly go in after them. I will glorify myself over Pharaoh and all his army, his chariots and horsemen. The Egyptians will know that I am the Lord when I glorify myself over Pharaoh, his chariots, and his horsemen.» Then the angel of God, who had been going in front of Israel, moved and went behind them. The pillar of cloud moved from the front and stood behind them, between the camp of the Egyptians and the camp of Israel. This cloud was both darkness and light during the night, so that all night long they could not come near each other. Moses stretched out his arm over the sea. The Lord drove the sea back all night with a strong east wind. He dried up the sea, and the waters were divided. The Israelites went into the midst of the sea on dry ground, the waters forming a wall to their right and to their left. The Egyptians pursued them. All Pharaoh's horses, his chariots, and his horsemen went in after them to the midst of the sea. In the last hours of the night, the Lord looked down on the Egyptian army from the pillar of fire and cloud, and he threw them into a panic. He jammed the wheels of their chariots, and they struggled to drive them. The Egyptians cried out, «Let us flee from Israel, for the Lord is fighting for them against us!» Then the Lord said to Moses, «Stretch out your hand over the sea so that the waters may return upon the Egyptians, their chariots, and their horsemen.» So Moses stretched out his hand over the sea, and at daybreak the sea returned to its place. As the Egyptians fled, they were struck by the waters, and the Lord swept them into the midst of the sea. The waters returned and covered the chariots and horsemen—all of Pharaoh’s army that had gone into the sea in pursuit of Israel. Not one of them was left. But the Israelites had walked on dry ground through the midst of the sea, the waters forming a wall to their right hand and to their left. That day the Lord saved Israel from the hand of the Egyptians, and Israel saw the Egyptians lying dead on the seashore. Israel saw the great power the Lord had displayed against Egypt. The people feared the Lord and put their trust in him and in his servant Moses. Then Moses and the Israelites sang this song to the Lord: R/ Let us sing to the Lord! His glory is exalted! I will sing to the Lord! His glory is exalted: he has hurled horse and rider into the sea. The Lord is my strength and my song. He is my salvation. He is my God, and I will praise him. I will exalt the God of my father. The Lord is a warrior. His name is «The Lord.» Pharaoh’s chariots and his armies he has hurled into the sea. The elite of their commanders have sunk in the Red Sea. The deep has covered them. They have sunk to the depths of the waters like a stone. Your right hand, Lord, is majestic in power; your right hand, Lord, crushes the enemy. You bring them in and plant them on your holy mountain, the place you have made to dwell in, Lord, the sanctuary your hands have established, Lord. The Lord will reign forever.
Walking on dry land: when God opens a path where there is none
The Crossing of the Sea of Reeds, or how divine power transforms the impossible into a passage to freedom
There are scenes in the Bible so profound, so imbued with divine power, that they transcend mere historical narrative to become a mirror of all human existence. The crossing of the Red Sea is one of them. There, on the water's edge, between approaching death and expanding impossibility, a people discovers that their God is not a mere spectator. This foundational text speaks to all those who have felt cornered, trapped between an oppressive past and a seemingly closed future. It tells them: the path opens when you move forward.
We will begin by placing this narrative in its context to grasp its full resonance. We will then analyze the theological heart of this passage: the glory of God manifested in salvation. Next, we will explore three major themes—faith as movement, the cloud as an ambivalent presence, and song as a response to grace. We will engage this text in dialogue with the great Christian spiritual tradition before offering concrete suggestions for living it out today.
A people caught between two abysses
To understand what the Israelites are experiencing in this passage from Exodus 14–15, we must go back a few steps. The Hebrew people have just left Egypt after centuries of servitude. Ten plagues have shaken Pharaoh's power. The night of Passover sealed the covenant of blood and liberation. But now, freedom, barely tasted, already seems doomed. Pharaoh has changed his mind—as he has done several times before—and he sends his chariots in pursuit of a people without an army, without military training, with women, children, the elderly, and flocks.
The Israelites find themselves in a geographically hopeless situation: the sea before them, the Egyptian army behind. It is an absolute impasse. And it is precisely in this impasse that the scene opens. Physical geography here becomes a spiritual geography: suffocation, panic, utter human impossibility. The Israelites cry out. They reproach Moses for having led them to their deaths in the desert. Murmuration—this recurring sin of the people on their journey toward the Promised Land—begins from this foundational moment.
The divine response is immediate, but it is disconcerting: «Why cry out to me? Command the Israelites to move forward!» This command is one of the most powerful verses in all of Scripture. God does not say, «Wait, I’ll handle it.» He says, «Go.» There is a theology of action in faith here that runs throughout the Bible and finds its most dramatic expression here.
The narrative structure of the passage is remarkably well-constructed. It alternates between divine actions and human responses, night and daybreak, the paralysis of the Egyptians and the march of the Hebrews, the return of the waters and the song of victory. Literarily, this story belongs to the genre of salvation epics, a genre well-known in the ancient Near East, but which is radically reworked here: it is not a human hero who triumphs, but the Lord himself who fights.
In the liturgical calendar of the Catholic Church, this text holds a prominent place in the Easter Vigil—the holiest night of the year. This is no coincidence. The Church Fathers very early on recognized in the crossing of the sea the symbol of baptism: passage through the waters, death of the old self, birth into a new life. The text of Exodus 14–15 is therefore not merely a narrative of national deliverance. It is a universal promise, reinterpreted and made present in every baptism, in every conversion, in every moment when a man or woman agrees to set out on a journey despite the apparent impossibility.
The excerpt concludes with a note of understated beauty: "The people feared the Lord, they put their faith in the Lord and in his servant Moses. Then Moses and the children of Israel sang this song." From the paralyzing fear of the beginning to the reverential awe that leads to the song—that is the entire movement of the passage.
The glory of God, the driving force of salvation
The central idea of this narrative is not, contrary to what one might think, the power of Moses or even the faith of Israel. The central idea is the glory of God. The text repeats this with remarkable emphasis: «I will glorify myself at the expense of Pharaoh and all his army.» «The Egyptians will know that I am the Lord, when I have glorified myself.» This formula, in Hebrew we-nikabbe-dah, It carries the idea of weight, density, and an imposing presence. Divine glory is not vanity: it is the revelation of what God truly is.
The central paradox of the text is striking: God glorifies himself precisely where everything seems to accuse him of absence or powerlessness. His people are trapped. The Egyptians are armed to the teeth. The sea is there, impassable. And it is in this very moment that God acts—not despite the desperate situation, but through it. Human impossibility is the fertile ground for divine manifestation.
This paradox is not anecdotal. It structures the entire biblical theology of deliverance. We find it in David facing Goliath, in the prophets who announce restoration in the heart of exile, in the Annunciation to a young girl in a remote Galilean village, in the cross as the site of victory. Each time, the same grammar: the human abyss as the condition of divine fullness.
But there is more. The text introduces a crucial theological nuance concerning the hardening of the Egyptians' hearts. God says, "I will cause the Egyptians to become obstinate." This formulation has long troubled readers and commentators. How can a just God harden the hearts of his adversaries in order to destroy them more effectively? The answer lies in the Hebrew understanding of divine causality. For the biblical thinking of that era, God is the primary cause of everything that happens, including free human decisions. Pharaoh hardened his heart of his own volition—this is made clear in other chapters of Exodus. But this free hardening is also, from the perspective of faith, part of the divine plan. Nothing escapes God, not even the stubborn resistance of those who oppose him.
The existential implications of this analysis are considerable. It tells the believer that their "Pharaohs"—their obstacles, adversaries, and fears—are not beyond God's gaze. Paradoxically, they are the very instruments through which liberating power will manifest itself. This is not an invitation to passivity, nor a justification of evil. It is an invitation to view trials differently: not as proof of God's absence, but as the potential site of a new revelation.

Faith as a movement: setting out before seeing
The first major lesson of this text is a lesson in spiritual kinesiology, so to speak. Faith here is not a tranquil, settled inner disposition. Faith is a movement of the body. «Command the children of Israel to set out!» The Hebrew yissa'u is an imperative of the verb NASA, which means to rise, to depart, to set in motion. There is something almost physical in this divine order.
What God asks of Israel in this moment of crisis is to walk toward the sea—before the sea parts. The text doesn't say that God first parted the sea, and then the people walked. The narrative dynamic suggests that the passage was created within the movement itself. Moses stretches out his arm—a liturgical gesture, a prophetic gesture—and then the east wind blows all night, and the waters part. The walking and the parting are simultaneous.
This narrative structure carries a profound spiritual message that the entire Christian mystical tradition has explored: you don't see the path before you walk it. You see it while you walk it. It is the faith of Abraham who leaves his country without knowing where he is going. It is the faith of the disciples who cast their nets on the word of Jesus. It is the faith of the prodigal son who gets up and goes to his father before he even sees him.
This presents a real challenge for all spiritual life. We often wait for the conditions to be right, for the path to be visible, for guarantees to be given, before we truly begin to believe. The text says: it's the opposite. The act of setting out creates the conditions. Not through psychological magic, not through a law of attraction: but because God is faithful to those who walk in trust.
This doesn't mean that faith is naive or reckless. Moses didn't send the people to drown. There is obedience to the Word heard, discernment, and direction. But in this direction, one must be willing to set out before seeing everything. Faith as movement is the opposite of faith as passive waiting.
The cloud: a presence that protects and separates
One detail in the text deserves particular attention: the moving pillar of cloud. «The angel of God, who had been walking in front of Israel, moved and walked behind them. The pillar of cloud moved from the vanguard and came to stand behind them, between the camp of the Egyptians and the camp of Israel.»
This movement of the cloud is theologically extraordinary. The divine presence, which had guided Israel since the beginning of the Exodus—symbolized by this pillar of cloud by day and fire by night—changes its position. It no longer guides: it protects. It interposes itself. And the text adds this magnificent paradoxical formulation: «This cloud was both darkness and light in the night.»
The same divine presence is darkness to the Egyptians and light to Israel. This is a fundamental image for understanding the logic of revelation throughout Scripture. God is not an abstract, universal light that illuminates everyone in the same way, regardless of their relationship to him. His presence is differentiating. It illuminates those who walk with him; it becomes opaque, even blinding, to those who oppose it.
John echoes this very logic in his prologue: «The light shines in the darkness, and the darkness has not overcome it.» And Paul, in his second letter to the Corinthians, says that the Gospel is «the aroma of life to those who are being saved, but the aroma of death to those who are perishing.» The same reality, perceived differently depending on whether one faces it or turns one's back on it.
This theme of the cloud as an ambivalent presence runs throughout Christian mysticism. Gregory of Nyssa, in the fourth century, meditated at length on the cloud at Sinai as a symbol of the knowledge of God: one enters the cloud to reach God, and this entry is an entry into darkness, into the stripping away of superficial certainties. The cloud is not the enemy of faith; it is its highest form. Apophatic theology—that which holds that God is always beyond what is said of Him—finds here one of its foundational images.
For Christians today, this speaks directly to periods of spiritual dryness, of inner darkness, when God seems absent. The cloud says: I am here, but I am here in a different way. Not as a comforting light, but as a presence that protects, that separates from danger, that prepares the way.

Singing as a response to grace: one cannot cross the sea without singing.
The text concludes with a note that, if read too quickly, might seem anecdotal: "Then Moses and the Israelites sang this song to the Lord." But this conclusion is in fact the theological high point of the passage. It reveals its profound purpose.
The entire narrative of the crossing leads to this song. Salvation is not achieved when one has crossed the sea on dry land; it is achieved when one sings. The song—the Song of the Sea, Or Shirat ha-yam In Hebrew, praise is the appropriate human response to divine action. There is no more fitting response to grace than praise.
This is not merely an intellectual or ethical response. It is an aesthetic and liturgical one. We sing because the reality of what has happened transcends ordinary words. We sing because gratitude needs a form, a rhythm, a melody. We sing because joy is an energy that yearns to be expressed.
Jewish tradition has made this canticle one of the most commented upon and sung texts in the liturgy. It is recited every morning in the Shaharit prayer. The Catholic Church sings it at the Easter Vigil, after the third reading, with a verse of response: «Let us sing to the Lord, glorious is his victory!» The fact that this text is integrated into the heart of Easter night reveals something essential: the resurrection of Christ is the ultimate crossing of the sea, and the appropriate response to this resurrection is, as with Moses, song.
There is also a crucial communal dimension to this song. «Moses and the Israelites sang.» It is not a solo song. It is a song of the entire people. Salvation was collective—we went through it together—and the response is collective. We do not emerge from hardship alone to go and sing in our own corner. We celebrate together. The community is both the place of passage and the place of praise.
In the light of the Fathers and the great tradition
The Crossing of the Sea of Reeds is one of the most commented-upon texts in the entire Christian tradition. From the earliest centuries, the Church Fathers saw in this story a prophetic figure of baptism and of Christian life as a whole.
Tertullian, at the turn of the 2nd and 3rd centuries, was one of the first to explicitly formulate this link: the water of the sea is a figure of baptismal water; Pharaoh is a figure of the devil; the liberation of Israel is a figure of the salvation of the baptized. This typological reading—which sees in the events of the Old Testament figures of what is fully realized in Christ—is at the heart of the Church Fathers' pedagogy.
Origen of Alexandria, a century later, considerably deepened this interpretation. For him, the crossing of the sea is not merely a symbol of baptism; it is a symbol of the entire spiritual journey. Israel leaves Egypt—it is converted. It crosses the sea—it receives baptism. It walks in the desert—it enters the life of faith, with its trials and temptations. It enters the Promised Land—it attains the fullness of life in God. Each stage of the Exodus narrative becomes, in Origen's reading, a stage on the soul's inner journey.
Gregory of Nyssa, in his Life of Moses — one of the pinnacles of early Christian spirituality — focuses particularly on the figure of Moses as the model of the contemplative. Moses, who stretches out his arm over the sea, is the image of the Christian who, through prayer and obedience to God, cooperates in the divine work. The extension of the staff is not magic; it is an act of instrumental faith, through which the power of God flows through human obedience.
Augustine, in his numerous sermons on the Exodus and in the City of God, He sees in the drowning of the Egyptians an image of Christ's victory over sin and death. Pharaoh's chariots and warriors represent the disordered powers—vices, passions, attachments—that the baptismal water is meant to engulf. The crossing on dry land is the life of grace that walks in the midst of the waters without drowning, without being swept away by the current of the world.
Closer to home, in the liturgical tradition, the Song of the Sea The hymn from Exodus 15 has always held a central place in the Church's prayer. Bernard of Clairvaux, in the 12th century, saw in this canticle the prototype of all true praise: it arises not from human effort, but from the unexpected encounter with grace. We do not sing because we have decided to sing; we sing because we have seen, because we have been saved, because the reality of God has overflowed the ordinary boundaries of existence.
The Marian dimension of this text has not escaped tradition either. Mary of Nazareth, in her Magnificat, adopts the exact same structure as the Canticle of Moses: God who overthrows the powerful, who liberates the lowly, who fulfills his promises. Mary is the new Miriam—the sister of Moses who sang on the other side of the sea—and her song is humanity's most complete response to God's liberating action.

Lectio divina
""The Lord said to Moses, 'Why are you crying out to me? Tell the Israelites to move forward.'" (Exodus 14:15)
God doesn't ask us to wait for the sea to part; he asks us to walk. Faith precedes the miracle, it doesn't follow it. Israel must advance toward the waters before seeing them part. And you, is there a sea before you toward which you still refuse to take the first step?
Lord, you part the waters for those who walk toward you. You do not let those who walk in trust sink. Grant me that first step I dare not take. Let my feet touch the dry ground of your promise. You are the God who opens a path where there is none.
Two walls of black water rise beneath the stars, and between them, a path of dry sand.
Enter the passage
The crossing of the Sea of Reeds is not merely a past event to be commemorated. It is an ongoing spiritual structure, a grammar of faith that every believer is called to reactivate in their own life. Here are some concrete ways to engage personally with this text.
Identify your sea. What reality in my current life seems insurmountable? What situation am I caught in, between an advancing threat and an impossibility before me? Naming this reality precisely is the first step to offering a genuine prayer to it.
Identify my temptation to murmur. The Israelites reproached Moses for leading them to their deaths. What is my own form of murmuring? Whom am I blaming for my situation? This inner movement, once identified, can be offered to God as honesty.
To receive the order to set off. Is there, in my life, a call to action that I am waiting to implement because the conditions do not yet seem favorable enough? The text encourages us to trust in the first step, even in the dark.
Look for the cloud. In my moments of spiritual dryness or trial, can I recognize a form of divine presence that is not a comfortable light, but discreet protection? The cloud does not dazzle; it accompanies.
Let the song come. Is there, in my recent history, a passage through which I have not yet given thanks? The text invites me to remember what God has done for me and to sing of it — aloud, in secret, in the liturgy, whatever the form.
Experiencing the community dimension. Do I live my faith in a community that sings together? Do I share difficult times as well as deliverances received with others?
The sea opens again
This account from Exodus 14–15 is one of those passages of Scripture that never grow old, because it speaks of something eternal in the human condition: the embrace of the impossible, and the surprise of deliverance. But what makes it unique is not its dramatic intensity—other texts have that. It is its theology of glory: God acts where no human action can, precisely so that what happens will be recognized as coming from him.
The transformative message of this passage is strikingly relevant today. It tells anyone cornered that the impasse is not the final word. It tells any community in crisis that the divine presence is shifting—it can leave the vanguard to come and protect the rear. It tells every seeker of God that faith is not primarily an intellectual certainty, but a movement, a beginning, a first step into the darkness.
And he says to all those who have endured hardship and who look back at the wreckage of what sought to destroy them, that the right response is neither revenge, nor analysis, nor even mere relief. The right response is song. Let us sing to the Lord, glorious is his victory. Horse and rider, he has cast them into the sea. And we, we walk on dry land.
