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.
12 Finally, Moses was so tired that Aaron and Hur got a rock for him to sit on. Then they stood beside him and supported his arms in the same position until sunset.
13 That's how Joshua defeated the Amalekites.
14 Afterwards, the Lord said to Moses, “Write an account of this victory and read it to Joshua. I want the Amalekites to be forgotten for ever.”
15 Moses built an altar and named it “The Lord Gives me Victory”.
16 Then Moses explained, “This is because I depended on the Lord. But in future generations, the Lord will have to fight the Amalekites again.”
