The LORD your God will help you capture the land, and he will give you peace. But when that day comes, you must wipe out Amalek so completely that no one will remember they ever lived.
The LORD will be furious, and instead of forgiving you, he will separate you from the other tribes. Then he will destroy you, by piling on you all the curses in The Book of God's Law, and you will be forgotten for ever.
