"Now when Moses stretched out his hand over the sea, the LORD made it retreat by a strong east wind all night, and made the sea dry and the waters parted. And the Israelites went in the middle of the sea on dry land, and the waters were a wall to their right and to their left.
And the Egyptians followed and went in after them, all Pharaoh's horses, his chariots and his men, into the middle of the sea. Moses, chapter 14, verse 21ff.
