19 Then the angel of God who was going before the host of Israel moved and went behind them, and the pillar of cloud moved from before them and stood behind them, 20 coming between the host of Egypt and the host of Israel. And there was the cloud and the darkness. And it lit up the night[1] without one coming near the other all night.

Matthew Henry's Commentary on Exodus 14:19-20

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.
