Exodus 14:21-24

21And Moses stretched out his hand over the sea; and Jehovah made the sea go [back] by a strong east wind all the night, and made the sea dry [land], and the waters were divided.

22And the children of Israel went through the midst of the sea on the dry [ground]; and the waters were a wall to them on their right hand and on their left.

23And the Egyptians pursued and came after them — all Pharaoh's horses, his chariots and his horsemen, into the midst of the sea.

24And it came to pass in the morning watch, that Jehovah looked upon the camp of the Egyptians, in the pillar of fire and of the cloud, and embarrassed the camp of the Egyptians.
