Exodus 17:14-16

BSB(i) 14 Then the LORD said to Moses, “Write this on a scroll as a reminder and recite it to Joshua, because I will utterly blot out the memory of Amalek from under heaven.” 15 And Moses built an altar and named it The LORD Is My Banner. 16 “Indeed,” he said, “a hand was lifted up toward the throne of the LORD. The LORD will war against Amalek from generation to generation.”
