Exodus 17:2-7

2So the people quarreled with Moses and said, “Give us water to drink.” And Moses said to them, “Why do you quarrel with me? Why do you test Adonai?”

3But the people thirsted for water there, and they complained against Moses and said, “Why have you brought us up out of Egypt? To kill us with thirst, along with our children and cattle?”

4So Moses cried out to Adonai saying, “What am I to do for these people? They are about ready to stone me.”

5Adonai said to Moses, “Walk before the people, and take of the elders of Israel with you, along with your staff with which you struck the river. Take it in your hand and go.

6Behold, I will stand before you, there upon the rock in Horeb. You are to strike the rock, and water will come out of it so that the people can drink.” Then Moses did just so in the eyes of the elders of Israel.

7The name of the place was called Massah and Meribah, because of the quarreling of Bnei-Yisrael, and because they tested Adonai saying, “Is Adonai among us, or not?”
