Exodus 17:5-7

New International Version

⁵ The Lord answered Moses, “Go out in front of the people. Take with you some of the elders of Israel and take in your hand the staff^(A) with which you struck the Nile,^(B) and go. ⁶ I will stand there before you by the rock at Horeb.^(C) Strike^(D) the rock, and water^(E) will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel. ⁷ And he called the place Massah^[a](F) and Meribah^[b](G) because the Israelites quarreled and because they tested the Lord saying, “Is the Lord among us or not?”
