Exodus 17:8-16 - Battle With The Amalekites

⁸ And Amalek came and fought with Israel at Rephidim. ⁹ And Moses said to Joshua, "Choose men for us, and go out, fight against Amalek tomorrow. I [will be] standing on the top of the hill, and the staff of God [will be] in my hand."

¹⁰ And Joshua did as Moses had said to him to fight with Amalek. And Moses, Aaron, and Hur went up [to] the top of the hill. ¹¹ And when Moses raised his hand, Israel would prevail, but when he rested his hand, Amalek would prevail. ¹² But the hands of Moses [were] heavy, and they took a stone and placed it under him, and he sat on it; Aaron and Hur supported his hands, {one on each side}, and his hands [were] steady until {sundown}. ¹³ And Joshua defeated Amalek and his people with [the] {edge of the sword}.

¹⁴ And Yahweh said to Moses, "Write this [as] a memorial in the scroll and {recite it in the hearing of} Joshua, because I will utterly blot out the remembrance of Amalek from under the heavens."

¹⁵ And Moses built an altar, and he called its name Yahweh [Is] My Banner. ¹⁶ And he said, "Because a hand [was] against the throne of Yah, a war [will be] for Yahweh with Amalek from generation [to] generation."
