Exodus 17:9-11

Lexham English Bible

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^[a] when Moses raised his hand, Israel would prevail, but when he rested his hand, Amalek would prevail.
