Exodus 17:1-2

Revised Standard Version

Water from the Rock

17 All the congregation of the people of Israel moved on from the wilderness of Sin by stages, according to the commandment of the Lord, and camped at Reph′idim; but there was no water for the people to drink. ² Therefore the people found fault with Moses, and said, “Give us water to drink.” And Moses said to them, “Why do you find fault with me? Why do you put the Lord to the proof?”
