Exodus 14:13-16, 26-27

But Moses told the people, “Don’t be afraid. Just stand still and watch the LORD rescue you today. The Egyptians you see today will never be seen again. The LORD himself will fight for you. Just stay calm.” Then the LORD said to Moses, “Why are you crying out to me? Tell the people to get moving! Pick up your staff and raise your hand over the sea. Divide the water so the Israelites can walk through the middle of the sea on dry ground.

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.
