Exodus 17:10-12

Living Bible

¹⁰ So Joshua and his men went out to fight the army of Amalek. Meanwhile Moses, Aaron, and Hur^[a] went to the top of the hill. ¹¹ And as long as Moses held up the rod in his hands, Israel was winning; but whenever he rested his arms at his sides, the soldiers of Amalek were winning. ¹² Moses’ arms finally became too tired to hold up the rod any longer; so Aaron and Hur rolled a stone for him to sit on, and they stood on each side, holding up his hands until sunset.
