Exodus 17:13-16 Living Bible (TLB)
13 As a result, Joshua and his troops crushed the army of Amalek, putting them to the sword.
14 Then the Lord instructed Moses, “Write this into a permanent record, to be remembered forever, and announce to Joshua that I will utterly blot out every trace of Amalek.” 15-16 Moses built an altar there and called it “Jehovah-nissi” (meaning “Jehovah is my flag”).
“Raise the banner of the Lord!” Moses said. “For the Lord will be at war with Amalek generation after generation.”
