Exodus 14:19-21 The Message (MSG)
19-20 The angel of God that had been leading the camp of Israel now shifted and got behind them. And the Pillar of Cloud that had been in front also shifted to the rear. The Cloud was now between the camp of Egypt and the camp of Israel. The Cloud enshrouded one camp in darkness and flooded the other with light. The two camps didn’t come near each other all night.
21 Then Moses stretched out his hand over the sea and God, with a terrific east wind all night long, made the sea go back. He made the sea dry ground. The seawaters split.
