Then G-d spoke to Moses: "Lift thou up thy rod, and stretch out thy hand over the sea and divide it; and the children of Israel shall go into the midst of the sea on dry ground."
Moses did as G-d ordered him. He raised his staff, and stretched his hand over the sea; a strong east wind rose and blew the whole night.
The waters of the Red Sea were immediately divided and gathered into a wall on either side, leaving a dry passage in the midst. The Israelites marched at once along that dry path which extended from shore to shore, and gained the opposite side in safety.
