Exodus 17:10-12

Revised Geneva Translation

¹⁰ So, Joshua did as Moses commanded him, and fought with Amalek. And Moses, Aaron, and Hur, went up to the top of the hill.

¹¹ And when Moses held up his hand, Israel prevailed. But when he let his hand down, Amalek prevailed.

¹² Now, Moses’ hands were heavy. Therefore, they took a stone and put it under him, and he sat upon it. And Aaron and Hur held up his hands, one on one side and the other on the other side. So, his hands were steady until the the sun went down.
