8 Then came Amalek and fought with Israel at Rephidim. 9 And Moses said to Joshua, “Choose for us men, and go out, fight with Amalek; tomorrow I will stand on the top of the hill with the rod of God in my hand.” 10 So Joshua did as Moses told him, and fought with Amalek; and Moses, Aaron, and Hur went up to the top of the hill. 11 Whenever Moses held up his hand, Israel prevailed; and whenever he lowered his hand, Amalek prevailed. 12 But Moses’ hands grew weary; so they took a stone and put it under him, and he sat upon it, and Aaron and Hur held up his hands, one on one side, and the other on the other side; so his hands were steady until the going down of the sun. 13 And Joshua mowed down Amalek and his people with the edge of the sword.
