Rev 15:3, Ex 15:17

After the Exodus, Moses praised God with the song of the Lamb. (Ex 15:1-8, Ex 15:16-20)

Ex 15:1 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. 2 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. 3 The Lord is a man of war: the Lord is his name. 4 Pharaoh's chariots and his host hath he cast into the sea: his chosen captains also are drowned in the Red sea. 5 The depths have covered them: they sank into the bottom as a stone. 6 Thy right hand, O Lord, is become glorious in power: thy right hand, O Lord, hath dashed in pieces the enemy. 7 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. 8 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.

Ex 15:16 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. 17 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. 18 The Lord shall reign for ever and ever. 19 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. 20 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.

Moses knew that God would send Christ as the Lamb of God. (Revelation 15:3)

Revelation 15:3 And they sing the song of Moses the servant of God, and the song of the Lamb, saying, Great and marvellous are thy works, Lord God Almighty; just and true are thy ways, thou King of saints.
