Exodus 17:14-16 NASB1995
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.” Moses built an altar and named it The LORD is My Banner; and he said, “The LORD has sworn; the LORD will have war against Amalek from generation to generation.”
