Exodus 14:20-22

New Revised Standard Version, Anglicised

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.

²¹ Then Moses stretched out his hand over the sea. The Lord drove the sea back by a strong east wind all night, and turned the sea into dry land; and the waters were divided. ²² The Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left.
