9. So Moses said to Joshua, “Choose some men and go and fight the Amalekites. Tomorrow I will stand on the top of the hill, holding the walking stick of God in my hands.”
10. Joshua obeyed Moses and went to fight the Amalekites, while Moses, Aaron, and Hur went to the top of the hill.
11. As long as Moses held his hands up, the Israelites would win the fight, but when Moses put his hands down, the Amalekites would win.
12. Later, when Moses’ arms became tired, the men put a large rock under him, and he sat on it. Then Aaron and Hur held up Moses’ hands—Aaron on one side and Hur on the other. They kept his hands steady until the sun went down.
13. So Joshua defeated the Amalekites in this battle.
14. Then the Lord said to Moses, “Write about this battle in a book so people will remember. And be sure to tell Joshua, because I will completely destroy the Amalekites from the earth.”
15. Then Moses built an altar and named it The Lord Is My Banner.
