Exodus 17:9–13
So Moses said to Joshua, “Choose some of our men and go out to fight the Amalekites. Tomorrow I will stand on the hilltop with the staff of God in my hand.” / Joshua did as Moses had instructed him and fought against the Amalekites, while Moses, Aaron, and Hur went up to the top of the hill. / As long as Moses held up his hands, Israel prevailed; but when he lowered them, Amalek prevailed.
