11So it came about, when Moses held his hand up, that Israel prevailed; but when he let his hand down, Amalek prevailed. 12And Moses’ hands were heavy. So they took a stone and put it under him, and he sat on it; and Aaron and Hur supported his hands, one on one side and one on the other. So his hands were steady until the sun set.
