21 And when Moses' hand was stretched out over the sea, the Lord with a strong east wind made the sea go back all night, and the waters were parted in two and the sea became dry land. 22 And the children of Israel went through the sea on dry land: and the waters were a wall on their right side and on their left. 23 Then the Egyptians went after them into the middle of the sea, all Pharaoh's horses and his war-carriages and his horsemen. 24 And in the morning watch, the Lord, looking out on the armies of the Egyptians from the pillar of fire and cloud, sent trouble on the army of the Egyptians; 25 And made the wheels of their war-carriages stiff, so that they had hard work driving them: so the Egyptians said, Let us go in flight from before the face of Israel, for the Lord is fighting for them against the Egyptians. 26 And the Lord said to Moses, Let your hand be stretched out over the sea, and the waters will come back again on the Egyptians, and on their war-carriages and on their horsemen. 27 And when Moses' hand was stretched out over the sea, at dawn the sea came flowing back, meeting the Egyptians in their flight, and the Lord sent destruction on the Egyptians in the middle of the sea. 28 And the waters came back, covering the war-carriages and the horsemen and all the army of Pharaoh which went after them into the middle of the sea; not one of them was to be seen. 29 But the children of Israel went through the sea walking on dry land, and the waters were a wall on their right side and on their left. 30 So that day the Lord gave Israel salvation from the hands of the Egyptians; and Israel saw the Egyptians dead on the sea's edge.

Commentary on Exodus 14:21-31
(Read Exodus 14:21-31)
The dividing the Red sea was the terror of the Canaanites, Isaiah 11:15; and the Egyptians being drowned in it was typical of the final ruin of all unrepenting sinners. God showed his almighty power, by opening a passage through the waters, some miles over. God can bring his people through the greatest difficulties, and force a way where he does not find it. It was an instance of his wonderful favour to his Israel. They went through the sea, they walked upon dry land in the midst of the sea. This was done, in order to encourage God's people in all ages to trust him in the greatest straits. What cannot he do who did this? What will not he do for those that fear and love him, who did this for these murmuring, unbelieving Israelites? Then followed the just and righteous wrath of God upon his and his people's enemies. The ruin of sinners is brought on by their own rage and presumption. They might have let Israel alone, and would not; now they would flee from the face of Israel, and cannot. Men will not be convinced, till it is too late, that those who meddle with God's people, meddle to their own hurt. Moses was ordered to stretch out his hand over the sea; the waters returned, and overwhelmed all the host of the Egyptians. Pharaoh and his servants, who had hardened one another in sin, now fell together, not one escaped. The Israelites saw the Egyptians dead upon the sands. The sight very much affected them. While men see God's works, and feel the benefit, they fear him and trust in him. How well were it for us, if we were always in as good a frame as sometimes! Behold the end to which a Christian may look forward. His enemies rage, and are mighty; but while he holds fast by God, he shall pass the waves in safety guarded by that very power of his Saviour, which shall come down on every spiritual foe. The enemies of his soul whom he hath seen to-day, he shall see no more for ever.
