Exodus 14:18-20 New Revised Standard Version Catholic Edition (NRSVCE)
18 And the Egyptians shall know that I am the Lord, when I have gained glory for myself over Pharaoh, his chariots, and his chariot drivers.”
19 The angel of God who was going before the Israelite army moved and went behind them; and the pillar of cloud moved from in front of them and took its place behind them. 20 It came between the army of Egypt and the army of Israel. And so the cloud was there with the darkness, and it lit up the night; one did not come near the other all night.
