While the people of Israel were still at Rephidim, the warriors of Amalek came to fight against them.
Moses commanded Joshua, "Call the Israelites to arms, and fight the army of Amalek. Tomorrow, I will stand at the top of the hill with the staff of God in my hand."
So Joshua did what Moses had commanded. He led his men out to fight the army of Amalek. Meanwhile Moses, Aaron, and Hur went to the top of a nearby hill.
As long as Moses held up the staff with his hands, the Israelites had the advantage. But whenever he lowered his hands, the Amalekites gained the upper hand.
Moses' arms finally became too tired to hold up the staff any longer. So Aaron and Hur found a stone for him to sit on. Then they stood on each side, holding up his hands until sunset.
As a result, Joshua and his troops were able to crush the army of Amalek.
