Exodus 14:21-23

21Moses stretched out his hand toward the sea, and the Lord drove the sea apart by a strong east wind all that night, and he made the sea into dry land, and the water was divided.

22So the Israelites went through the middle of the sea on dry ground, the water forming a wall for them on their right and on their left.

23The Egyptians chased them and followed them into the middle of the sea – all the horses of Pharaoh, his chariots, and his horsemen.
