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.
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.
