Exodus 14:27-31

27 Moses stretched out his hand over the sea, and at daybreak the sea went back to its place. The Egyptians were fleeing towarda it, and the LORD swept them into the sea.
28 The water flowed back and covered the chariots and horsemen—the entire army of Pharaoh that had followed the Israelites into the sea. Not one of them survived.
29 But the Israelites went through the sea on dry ground, with a wall of water on their right and on their left.
30 That day the LORD saved Israel from the hands of the Egyptians, and Israel saw the Egyptians lying dead on the shore.
31 And when the Israelites saw the mighty hand of the LORD displayed against the Egyptians, the people feared the LORD and put their trust in him and in Moses his servant.
