13 So Joshua overwhelmed Amalek and his people with the edge of the sword.
14 Then the Lord said to Moses, "Write this in a book as a memorial and recite it to Joshua, that I will utterly blot out the memory of Amalek from under heaven."
15 Moses built an altar and named it The Lord is My Banner;
16 and he said, "The Lord has sworn; the Lord will have war against Amalek from generation to generation."
