4 So Moses cried out to the Lord, saying, "What shall I do to this people? A little more and they will stone me."
5 Then the Lord said to Moses, "Pass before the people and take with you some of the elders of Israel; and take in your hand your staff with which you struck the Nile, and go.
6 Behold, I will stand before you there on the rock at Horeb; and you shall strike the rock, and water will come out of it, that the people may drink." And Moses did so in the sight of the elders of Israel.
7 He named the place Massah and Meribah because of the quarrel of the sons of Israel, and because they tested the Lord, saying, "Is the Lord among us, or not?"
8 Then Amalek came and fought against Israel at Rephidim.
9 So Moses said to Joshua, "Choose men for us and go out, fight against Amalek. Tomorrow I will station myself on the top of the hill with the staff of God in my hand."
10 Joshua did as Moses told him, and fought against Amalek; and Moses, Aaron, and Hur went up to the top of the hill.
