Exodus 17:9-11

Revised Geneva Translation

⁹ And Moses said to Joshua, “Pick out men for us, and go fight with Amalek. Tomorrow, I will stand on the top of the hill with the rod of God in my hand.”

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.
