Exodus 14:19-21 Living Bible (TLB)
19 Then the Angel of God, who was leading the people of Israel, moved the cloud around behind them, 20 and it stood between the people of Israel and the Egyptians. And that night, as it changed to a pillar of fire, it gave darkness to the Egyptians but light to the people of Israel! So the Egyptians couldn’t find the Israelis!
21 Meanwhile, Moses stretched his rod over the sea, and the Lord opened up a path through the sea, with walls of water on each side; and a strong east wind blew all that night, drying the sea bottom.
