Exodus 14:28-31

28And the waters returned, and covered the chariots and the horsemen of all the host of Pharaoh that had come into the sea after them; there remained not even one of them. 29And the children of Israel walked on dry [ground] through the midst of the sea; and the waters were a wall to them on their right hand and on their left. 30Thus Jehovah saved Israel that day out of the hand of the Egyptians; and Israel saw the Egyptians dead on the sea-shore. 31And Israel saw the great power [with] which Jehovah had wrought against the Egyptians; and the people feared Jehovah, and believed in Jehovah, and in Moses his bondman.
