Exodus 17:14-16

14Then the Lord said to Moses, “Write this as a memorial in a book and recite it in the ears of aJoshua, that bI will utterly blot out the memory of Amalek from under heaven.” 15And Moses cbuilt an altar and called the name of it, The Lord Is My Banner, 16saying, “A hand upon the throne
A slight change would yield  upon the banner
of the Lord! eThe Lord will have war with Amalek from generation to generation.”
