Exodus 14:16

But lift thou up thy rod, the same shepherd's staff that had figured so largely in Egypt, and stretch out thine hand over the sea, and divide it. He was not merely to cause an unusually low ebb-tide, together with a strong wind to hold the water back, but he was to separate, to cut apart, the waters of the sea, the purpose of the wind afterward being merely to assist in drying off the bottom of the sea. And the children of Israel shall go on dry ground through the midst of the sea.
