Exodus 17:9-13 And Moses said to Joshua, Choose us men, and go out, fight with Amalek; to-morrow I will stand on the top of the hill with the staff of God in my hand.

Darby⁽ⁱ⁾ ⁹ And Moses said to Joshua, Choose us men, and go out, fight with Amalek; to-morrow I will stand on the top of the hill with the staff of God 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 it came to pass when Moses raised his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed. ¹² And Moses` hands were heavy; then they took a stone, and put [it] under him, and he sat on it; and Aaron and Hur supported his hands, one on this side, and one on that side; and his hands were steady until the going down of the sun. ¹³ And Joshua broke the power of Amalek and his people with the edge of the sword.
