Exodus 17:1-6

¹All 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. ²Therefore 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?" ³But the people thirsted there for water, and the people murmured against Moses, and said, "Why did you bring us up out of Egypt, to kill us and our children and our cattle with thirst?" ⁴So Moses cried to the LORD, "What shall I do with this people? They are almost ready to stone me." ⁵And the LORD said to Moses, "Pass on before the people, taking with you some of the elders of Israel; and take in your hand the rod with which you struck the Nile, and go. ⁶Behold, I will stand before you there on the rock at Horeb; and you shall strike the rock, and water shall come out of it, that the people may drink." And Moses did so, in the sight of the elders of Israel.
