19 Then the angel of God, who had been leading the people of Israel, moved to the rear of the camp. The pillar of cloud also moved from the front and stood behind them. 20 The cloud settled between the Egyptian and Israelite camps. As darkness fell, the cloud turned to fire, lighting up the night. But the Egyptians and Israelites did not approach each other all night.

21 Then Moses raised his hand over the sea, and the Lord opened up a path through the water with a strong east wind. The wind blew all that night, turning the seabed into dry land. 22 So the people of Israel walked through the middle of the sea on dry ground, with walls of water on each side!

Matthew Henry's Commentary on Exodus 14:19-22

Commentary on Exodus 14:15-20

(Read Exodus 14:15-20)

Moses' silent prayers of faith prevailed more with God than Israel's loud outcries of fear. The pillar of cloud and fire came behind them, where they needed a guard, and it was a wall between them and their enemies. The word and providence of God have a black and dark side toward sin and sinners, but a bright and pleasant side toward the people of the Lord. He, who divided between light and darkness, Genesis 1:4, allotted darkness to the Egyptians, and light to the Israelites. Such a difference there will be between the inheritance of the saints in light, and that utter darkness which will be the portion of hypocrites for ever.

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.
