Exodus 14:10-31

In the Easter Vigil, the priest says, "O God, who caused the children of Abraham to pass dry-shod through the Red Sea,so that the chosen people, set free from slavery to Pharaohh, would prefigure the people of the baptized.

14-16:

The Lord will fight for you: you have only to keep still.

Then The Lord said to Moses: Why are you crying out to me? tell the Israelites to set out.

And you, lift up your staff and stretch out your hand over the sea, and split it in two, that the Israelites may pass through the sea on dry land.
