Exodus 17:11-13

Holman Christian Standard Bible

¹¹ While Moses held up his hand,^[a] Israel prevailed, but whenever he put his hand^[b] down, Amalek prevailed.^{(A) 12} When Moses’ hands grew heavy, they took a stone and put it under him, and he sat down on it. Then Aaron and Hur supported his hands, one on one side and one on the other so that his hands remained steady until the sun went down. ¹³ So Joshua defeated Amalek and his army^[c] with the sword.
