Exodus 14:21-23

Then Moses stretched out his hand over the sea; and the LORD swept the sea back by a strong east wind all night and turned the sea into dry land, so the waters were divided. The sons of Israel went through the midst of the sea on the dry land, and the waters were like a wall to them on their right hand and on their left. Then the Egyptians took up the pursuit, and all Pharaoh’s horses, his chariots and his horsemen went in after them into the midst of the sea.
