Exodus 17:8-10

Amplified Bible, Classic Edition

⁸ Then came Amalek [descendants of Esau] and fought with Israel at Rephidim.

⁹ And Moses said to Joshua, Choose us out men and go out, 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 said and fought with Amalek; and Moses, Aaron, and Hur went up to the hilltop.
