Exodus 17:5-13

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?”

The Amalekites Defeated

⁸ The Amalekites^(H) came and attacked the Israelites at Rephidim.^{(I) 9} Moses said to Joshua,^(J) “Choose some of our men and go out to fight the Amalekites. Tomorrow I will stand on top of the hill with the staff^(K) of God in my hands.”

¹⁰ So Joshua fought the Amalekites as Moses had ordered, and Moses, Aaron and Hur^(L) went to the top of the hill. ¹¹ As long as Moses held up his hands, the Israelites were winning,^(M) but whenever he lowered his hands, the Amalekites were winning. ¹² When Moses’ hands grew tired, they took a stone and put it under him and he sat on it. Aaron and Hur held his hands up—one on one side, one on the other—so that his hands remained steady till sunset.^{(N) 13} So Joshua overcame the Amalekite^(O) army with the sword.
