First reading
In the wilderness the people thirsted for water; and the people complained against Moses and said, “Why did you bring us out of Egypt, to kill us and our children and livestock with thirst?” So Moses cried out to the Lord, “What shall I do with this people? They are almost ready to stone me.”
The Lord said to Moses, “Go on ahead of the people, and take some of the elders of Israel with you; take in your hand the staff with which you struck the Nile, and go. I will be standing there in front of you on the rock at Horeb. Strike the rock, and water will come out of it, so that the people may drink.” Moses did so, in the sight of the elders of Israel.
He called the place Massah and Meribah, because the children of Israel quarrelled and tested the Lord, saying, “Is the Lord among us or not?”
