Exodus 14:27-29

14:27 So Moses extended his hand toward the sea, and the sea returned to its normal state when the sun began to rise. Now the Egyptians were fleeing before it, but the Lord overthrew the Egyptians in the middle of the sea. 14:28 The water returned and covered the chariots and the horsemen and all the army of Pharaoh that was coming after the Israelites into the sea – not so much as one of them survived! 14:29 But the Israelites walked on dry ground in the middle of the sea, the water forming a wall for them on their right and on their left.
