Exodus 14:26-29

When all the Israelites had reached the other side, the LORD said to Moses, “Raise your hand over the sea again. Then the waters will rush back and cover the Egyptians and their chariots and charioteers.” So as the sun began to rise, Moses raised his hand over the sea, and the water rushed back into its usual place. The Egyptians tried to escape, but the LORD swept them into the sea. Then the waters returned and covered all the chariots and charioteers—the entire army of Pharaoh. Of all the Egyptians who had chased the Israelites into the sea, not a single one survived. But the people of Israel had walked through the middle of the sea on dry ground, as the water stood up like a wall on both sides.
