Exodus 17:11-13

Amplified Bible, Classic Edition

¹¹ When Moses held up his hand, Israel prevailed; and when he lowered his hand, Amalek prevailed.

¹² But Moses’ hands were heavy and grew weary. So [the other men] took a stone and put it under him and he sat on it. Then Aaron and Hur held up his hands, one on one side and one on the other side; so his hands were steady until the going down of the sun.

¹³ And Joshua mowed down and disabled Amalek and his people with the sword.
