8. When the Israelites were at Rephidim, they were attacked by the Amalekites.
9. So Moses told Joshua, “Have some men ready to attack the Amalekites tomorrow. I will stand on a hilltop, holding this walking stick that has the power of God.”
10. Joshua led the attack as Moses had commanded, while Moses, Aaron, and Hur stood on the hilltop.
11. The Israelites out-fought the Amalekites as long as Moses held up his arms, but they started losing whenever he had to lower them.
