Exodus 14:27-31

So Moses reached out with his hand over the sea, and the sea returned to its normal state at daybreak, while the Egyptians were fleeing right into it; then the Lord overthrew the Egyptians in the midst of the sea.

The waters returned and covered the chariots and the horsemen, Pharaoh’s entire army that had gone into the sea after them; not even one of them remained.

But the sons of Israel walked on dry land through the midst of the sea, and the waters were like a wall to them on their right and on their left.

So the Lord saved Israel that day from the hand of the Egyptians, and Israel saw the Egyptians dead on the seashore.

When Israel saw the great power which the Lord had used against the Egyptians, the people feared the Lord, and they believed in the Lord and in His servant Moses.
