Exodus 14:21-23

Then Moses stretched out his hand over the sea, and the LORD drove the sea back by a strong east wind all night and made the sea dry land, and the waters were divided. And the people of Israel went into the midst of the sea on dry ground, the waters being a wall to them on their right hand and on their left. The Egyptians pursued and went in after them into the midst of the sea, all Pharaoh’s horses, his chariots, and his horsemen.
