Israel Defeats the Amalekites

⁸ While the people of Israel were still at Rephidim, the warriors of Amalek attacked them. ⁹ Moses commanded Joshua, “Choose some men to go out and fight the army of Amalek for us. Tomorrow, I will stand at the top of the hill, holding the staff of God in my hand.”

¹⁰ So Joshua did what Moses had commanded and fought the army of Amalek. Meanwhile, Moses, Aaron, and Hur climbed to the top of a nearby hill. ¹¹ As long as Moses held up the staff in his hand, the Israelites had the advantage. But whenever he dropped his hand, the Amalekites gained the advantage. ¹² Moses’ arms soon became so tired he could no longer hold them up. So Aaron and Hur found a stone for him to sit on. Then they stood on each side of Moses, holding up his hands. So his hands held steady until sunset. ¹³ As a result, Joshua overwhelmed the army of Amalek in battle.

¹⁴ After the victory, the Lord instructed Moses, “Write this down on a scroll as a permanent reminder, and read it aloud to Joshua: I will erase the memory of Amalek from under heaven.” ¹⁵ Moses built an altar there and named it Yahweh-Nissi (which means “the Lord is my banner”). ¹⁶ He said, “They have raised their fist against the Lord’s throne, so now^[a] the Lord will be at war with Amalek generation after generation.”
