Exodus 14:26-29

26Then the LORD said to Moses, “Stretch out your hand over the sea, that the water may come back upon the Egyptians, upon their chariots, and upon their horsemen.” 27So Moses stretched out his hand over the sea, and the sea returned to its normal course when the morning appeared. And as the Egyptians fled into it, the LORD threw the Egyptians into the midst of the sea. 28The waters returned and covered the chariots and the horsemen; of all the host of Pharaoh that had followed them into the sea, not one of them remained. 29But the people of Israel walked on dry ground through the sea, the waters being a wall to them on their right hand and on their left.
