Exodus 17:13-15 Easy-to-Read Version (ERV)
13 So Joshua and his men defeated the Amalekites in this battle.
14 Then the Lord said to Moses, “Write about this battle. Write these things in a book so that people will remember what happened here. And be sure to tell Joshua that I will completely destroy the Amalekites from the earth.”
15 Then Moses built an altar and named it, “The Lord is My Flag.”
