Verse-by-Verse Commentary
The Book of Exodus
Chapter 15: The Song of Moses
Redemption breaks into song. On the far shore of the sea, with Egypt drowned behind them, Moses and Israel sing the first song in the Bible: "I will sing unto the LORD, for he hath triumphed gloriously." They praise the God who is their strength and salvation, the man of war whose right hand shattered the enemy, the incomparable One, "Who is like unto thee, O LORD," who will reign for ever and ever. Miriam and the women answer with timbrels and dances. Then, only three days later, the redeemed reach the bitter waters of Marah and murmur, and God shows Moses a tree that makes the bitter waters sweet, revealing Himself as "the LORD that healeth thee," before leading them to the wells and palms of Elim. Exodus 15 is a chapter about the song that redemption sings, the one God who has no equal, and the God who turns bitterness sweet and heals His people.

Setting the Stage
Strength and Song
The redeemed burst into the Bible's first song: "The LORD is my strength and song, and he is become my salvation."
Who Is Like Unto Thee?
The song exalts the one God without equal, glorious in holiness, who overthrew the enemy and reigns for ever and ever.
Miriam's Timbrel
Miriam and the women answer the song with timbrels and dances; the whole redeemed community lifts its praise to God.
The Bitter Made Sweet
Three days later the water is bitter, but a tree cast in makes it sweet, and God reveals Himself: "I am the LORD that healeth thee."
The LORD Is My Strength and Song (Exodus 15:1-8)
On the far shore the redeemed lift the first song in Scripture, praising the LORD who triumphed gloriously and cast horse and rider into the sea.
He Is Become My Salvation
"Then sang Moses and the children of Israel this song unto the LORD, and spake, saying, I will sing unto the LORD, for he hath triumphed gloriously: the horse and his rider hath he thrown into the sea. The LORD is my strength and song, and he is become my salvation: he is my God, and I will prepare him an habitation; my father's God, and I will exalt him. The LORD is a man of war: the LORD is his name. Pharaoh's chariots and his host hath he cast into the sea: his chosen captains also are drowned in the Red sea. The depths have covered them: they sank into the bottom as a stone. Thy right hand, O LORD, is become glorious in power: thy right hand, O LORD, hath dashed in pieces the enemy. And in the greatness of thine excellency thou hast overthrown them that rose up against thee: thou sentest forth thy wrath, which consumed them as stubble. And with the blast of thy nostrils the waters were gathered together, the floods stood upright as an heap, and the depths were congealed in the heart of the sea. The enemy said, I will pursue, I will overtake, I will divide the spoil; my lust shall be satisfied upon them; I will draw my sword, my hand shall destroy them. Thou didst blow with thy wind, the sea covered them: they sank as lead in the mighty waters."
Explanation
The moment the enemy is drowned, redemption breaks into music. This is the first recorded song in the Bible, and it is a song of salvation, sung "unto the LORD." Its theme is not Israel's courage but God's triumph: "he hath triumphed gloriously: the horse and his rider hath he thrown into the sea." At its heart stands the confession, "The LORD is my strength and song, and he is become my salvation." God was not only their rescuer; He had become their salvation, personally theirs. So they resolve, "I will prepare him an habitation ... and I will exalt him." The song then recounts the victory: Pharaoh's chariots cast into the sea, the captains drowned, the enemy sinking "as a stone," God's "right hand" glorious in power, His wrath consuming the foe like stubble. Every line lifts the eyes off the delivered and onto the Deliverer.
Hebrew Study
"The LORD is a man of war: the LORD is his name" (verse 3). "The LORD" stands for the sacred name YHWH, the name God revealed to Moses at the bush as "I AM THAT I AM," the self-existent, eternal One. The song does not praise many gods but exalts the one LORD by His own name. And the phrase "he is become my salvation" uses the Hebrew yeshuah, the root of the name Jesus, so that the very name of God the redeemed sang would one day be borne in the flesh by the Saviour who saves His people.
Gospel Focus
Redemption makes a people sing. There was no song in Egypt, only the groaning of slaves; but on the far side of the sea the redeemed lift their voices. So it is with salvation: God "hath put a new song in my mouth, even praise unto our God" (Psalm 40:3). And notice the note the song strikes, "he is become my salvation." It is not enough to know that God saves in general; faith says "my salvation," making the great deliverance personal. The same confession echoes down the Scriptures: "The LORD is my strength and song, and is become my salvation" (Psalm 118:14). This is the language of a heart that has been through the sea. When God has truly brought us out, we do not merely admire His power; we sing that He has become ours. The redeemed of the Lord are a singing people, and their song is not about themselves but about the LORD who triumphed for them.
Who Is Like Unto Thee (Exodus 15:9-18)
The song contrasts the enemy's proud boast with God's effortless overthrow, exalting the incomparable LORD who leads His redeemed and reigns for ever and ever.
Glorious in Holiness
"Who is like unto thee, O LORD, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders? Thou stretchedst out thy right hand, the earth swallowed them. Thou in thy mercy hast led forth the people which thou hast redeemed: thou hast guided them in thy strength unto thy holy habitation. The people shall hear, and be afraid: sorrow shall take hold on the inhabitants of Palestina. Then the dukes of Edom shall be amazed; the mighty men of Moab, trembling shall take hold upon them; all the inhabitants of Canaan shall melt away. Fear and dread shall fall upon them; by the greatness of thine arm they shall be as still as a stone; till thy people pass over, O LORD, till the people pass over, which thou hast purchased. Thou shalt bring them in, and plant them in the mountain of thine inheritance, in the place, O LORD, which thou hast made for thee to dwell in, in the Sanctuary, O Lord, which thy hands have established. The LORD shall reign for ever and ever. For the horse of Pharaoh went in with his chariots and with his horsemen into the sea, and the LORD brought again the waters of the sea upon them; but the children of Israel went on dry land in the midst of the sea."
Hebrew Study
The Song's central cry is a question that answers itself: "Who is like unto thee, O LORD, among the gods?" — mi-khamokha, the very phrase behind the names Micah and Michael, "who is like God?" He is "glorious in holiness" (ne'dar ba-qodesh). And the song ends with the first proclamation of God's everlasting kingship in Scripture: "The LORD shall reign for ever and ever" (YHWH yimlokh le-olam va'ed) — sung by ex-slaves on the far shore, before there is a temple, a throne, or a king.
Explanation
The song sets the enemy's boasting against God's power. The enemy had said, "I will pursue, I will overtake, I will divide the spoil ... my hand shall destroy them", six proud "I wills." But God simply "didst blow with thy wind, the sea covered them: they sank as lead." All the enemy's boasting was undone by a breath. Then rises the great question, "Who is like unto thee, O LORD, among the gods? who is like thee, glorious in holiness, fearful in praises, doing wonders?" None compares to Him. The song looks forward too: God "in thy mercy hast led forth the people which thou hast redeemed," and will bring them to "thy holy habitation" and plant them "in the mountain of thine inheritance." The nations, Palestina, Edom, Moab, Canaan, will hear and melt with fear. And it crowns everything with the eternal truth: "The LORD shall reign for ever and ever."
Gospel Focus
"Who is like unto thee, O LORD?" This is the cry of true worship: the incomparable greatness of the one God. The idols of Egypt had just been judged, and there was no rival left standing. "Who is a God like unto thee, that pardoneth iniquity" (Micah 7:18), glorious in holiness, awesome in the praises of His people, alone doing wonders. And the song ends where all history ends: "The LORD shall reign for ever and ever." The reign of God is the last word. It is no accident that this very song is sung again at the end of the Bible, where the redeemed stand by a sea of glass and sing "the song of Moses the servant of God, and the song of the Lamb" (Revelation 15:3), for the God who reigned at the Red Sea is the God who reigns at the end, and "the Lord God omnipotent reigneth" (Revelation 19:6). The One who has no equal, who drowned the enemy with a breath, reigns for ever, and His redeemed will be singing His praise when time is no more.
Miriam and the Women (Exodus 15:19-21)
Miriam takes a timbrel, and all the women follow with music and dancing, so the whole redeemed community joins the song of victory.
Sing Ye to the LORD
"And Miriam the prophetess, the sister of Aaron, took a timbrel in her hand; and all the women went out after her with timbrels and with dances. And Miriam answered them, Sing ye to the LORD, for he hath triumphed gloriously; the horse and his rider hath he thrown into the sea. So Moses brought Israel from the Red sea, and they went out into the wilderness of Shur; and they went three days in the wilderness, and found no water. And when they came to Marah, they could not drink of the waters of Marah, for they were bitter: therefore the name of it was called Marah. And the people murmured against Moses, saying, What shall we drink?"
Hebrew Study
Miriam is called "the prophetess" (nevi'ah) — the first woman so named in Scripture — and she leads the women with timbrel and dance: "Sing ye to the LORD, for he hath triumphed gloriously." Yet three days later the singing meets Marah, "bitter" (marah), where the water cannot be drunk. God shows Moses a tree, and cast into the bitter water it makes it sweet — an old picture of the tree of Calvary, by which the bitterest waters of life are made sweet. "There he proved them" (nissah, tested).
Explanation
After recalling that "the horse of Pharaoh went in with his chariots ... into the sea" while "the children of Israel went on dry land," the praise overflows into the whole camp. Miriam, called "the prophetess" and "the sister of Aaron," takes a timbrel, and "all the women went out after her with timbrels and with dances." Miriam leads them in answering the men's song with the same refrain: "Sing ye to the LORD, for he hath triumphed gloriously." The worship is not the private act of one leader but the joyful response of the entire redeemed people, men and women together, lifting music and dance to the God who saved them. Deliverance had made them a congregation of praise.
Gospel Focus
The praise of the redeemed is meant to be shared. It began with Moses and the men, and it spread through Miriam to all the women, until the whole camp was singing and rejoicing. Worship is contagious; one grateful heart kindles many. Here is a picture of the gathered people of God giving thanks together, "speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord" (Ephesians 5:19). God gives His people gladness, and it is right that redemption be celebrated with the whole heart and the whole congregation. The same God who split the sea deserves not a quiet, private nod but the full-throated, joyful praise of all His people. When we consider what the Lord has done, holding back our praise is a strange thing indeed; the redeemed at the sea did not, and neither should we.
The LORD That Healeth Thee (Exodus 15:22-27)
Three days from the song, the redeemed reach bitter water and murmur; God shows Moses a tree to make it sweet, reveals Himself as their healer, and leads them on to the wells of Elim.
There He Proved Them
"And he cried unto the LORD; and the LORD shewed him a tree, which when he had cast into the waters, the waters were made sweet: there he made for them a statute and an ordinance, and there he proved them, And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee. And they came to Elim, where were twelve wells of water, and threescore and ten palm trees: and they encamped there by the waters."
Explanation
The song was barely finished. Israel goes "three days in the wilderness, and found no water," and when they reach Marah, the water is too bitter to drink. So soon after the mountaintop, they meet a bitter valley, and "the people murmured against Moses, saying, What shall we drink?" Moses cries to the LORD, who "shewed him a tree, which when he had cast into the waters, the waters were made sweet." There God gave them "a statute and an ordinance," and "proved them," tested their hearts, promising that if they would hearken and obey, "I will put none of these diseases upon thee ... for I am the LORD that healeth thee." From Marah they journey to Elim, "where were twelve wells of water, and threescore and ten palm trees," a place of rest and abundance. God led them through the bitter place to the springs beyond.
Hebrew Study
"Marah" means bitter, so the place was named for its waters. And in verse 26 God reveals a covenant name for Himself: "I am the LORD that healeth thee," Hebrew YHWH Rophe, the LORD your healer. It is the first time God calls Himself the Healer, and He does it not in a hospital but at a bitter spring, teaching that the same God who tests His people is the God who heals them, in body and in soul.
Gospel Focus
Marah teaches that the road of the redeemed has bitter places, and often soon after great triumphs. Within three days of the Red Sea song, Israel faced undrinkable water. The Christian life is not one unbroken victory; God leads us through Marahs to prove us, to see whether we will trust and obey when the water turns bitter. And the cure is beautiful: a tree cast into the bitter waters made them sweet. The tree points to the cross, for "who his own self bare our sins in his own body on the tree" (1 Peter 2:24). When the tree of Calvary is cast into the bitter waters of our lives, they are made sweet; there is no bitterness the cross cannot heal. And at Marah God reveals Himself as "the LORD that healeth thee," the God "who healeth all thy diseases" (Psalm 103:3), healer of body and soul. Then He brings them to Elim, twelve wells and seventy palms. God never leaves His people at Marah. He leads them through the testing to the springs beyond, for the bitter place is a passage, not a home.
Chapter 15 in Review
Exodus 15 opens with the Song of Moses, the first song in the Bible, sung by the redeemed on the far shore of the sea. It exalts the LORD who "triumphed gloriously," their "strength and song" who "is become my salvation," the incomparable One, "Who is like unto thee, O LORD," glorious in holiness, who leads His redeemed and "shall reign for ever and ever." Miriam and the women answer with timbrels and dances, and the whole camp rejoices. Then, only three days later, Israel reaches the bitter waters of Marah and murmurs; God shows Moses a tree that makes the water sweet, reveals Himself as "the LORD that healeth thee," and leads them to the wells and palms of Elim.
For the Apostolic reader, this chapter is full of gospel. Redemption makes a people sing, and their song is not of themselves but of the LORD who became their salvation, the very name borne by Jesus. It exalts the one God without equal, whose reign is the last word of history, so that the redeemed will one day sing this same song of Moses and of the Lamb. It shows praise overflowing through the whole congregation. And it teaches that the road home has bitter places soon after its triumphs, where God proves us, but the tree of the cross cast into our bitterness makes it sweet, and the LORD our healer leads us through Marah to Elim. Sing to the LORD, trust Him at the bitter spring, and follow Him to the wells beyond.

Questions for Reflection
- The redeemed sang, "he is become my salvation." Have you made God's salvation personal, or do you only admire it from a distance?
- Marah came three days after the song. How do you respond when a bitter trial follows soon after a spiritual victory?
- God revealed Himself as "the LORD that healeth thee." Where do you need to bring the tree of the cross to make a bitter place sweet?
