Exodus 17:1-2

Then all the congregation of the children of Israel moved on from the Wilderness of Sin by stages, according to the commandment of the LORD, and camped at Rephidim, but there was no water for the people to drink. Therefore the people quarreled with Moses and said, “Give us water so we may [have something to] drink.” And Moses said to them, “Why do you quarrel with me? Why do you tempt the LORD and try His patience?”
