21 Then Moses stretched out his hand over the sea. The Lord drove the sea back by a strong east wind all night, and turned the sea into dry land; and the waters were divided. 22The Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left. 23The Egyptians pursued, and went into the sea after them, all of Pharaohs horses, chariots, and chariot drivers. 24At the morning watch the Lord in the pillar of fire and cloud looked down upon the Egyptian army, and threw the Egyptian army into panic. 25He clogged their chariot wheels so that they turned with difficulty. The Egyptians said, Let us flee from the Israelites, for the Lord is fighting for them against Egypt.
26 Then the Lord said to Moses, Stretch out your hand over the sea, so that the water may come back upon the Egyptians, upon their chariots and chariot drivers. 27So Moses stretched out his hand over the sea, and at dawn the sea returned to its normal depth. As the Egyptians fled before it, the Lord tossed the Egyptians into the sea. 28The waters returned and covered the chariots and the chariot drivers, the entire army of Pharaoh that had followed them into the sea; not one of them remained. 29But the Israelites walked on dry ground through the sea, the waters forming a wall for them on their right and on their left.
30 Thus the Lord saved Israel that day from the Egyptians; and Israel saw the Egyptians dead on the seashore. 31Israel saw the great work that the Lord did against the Egyptians. So the people feared the Lord and believed in the Lord and in his servant Moses.
15Then Moses and the Israelites sang this song to the Lord:
I will sing to the Lord, for he has triumphed gloriously;
horse and rider he has thrown into the sea.
