Just as it pleased the LORD to make you prosper and multiply, so also it will please Him to annihilate you and destroy you. And you will be uprooted from the land you are entering to possess.
KJV
And it shall come to pass, [that] as the LORD rejoiced over you to do you good, and to multiply you; so the LORD will rejoice over you to destroy you, and to bring you to nought; and ye shall be plucked from off the land whither thou goest to possess it.
ASV
And it shall come to pass, that, as Jehovah rejoiced over you to do you good, and to multiply you, so Jehovah will rejoice over you to cause you to perish, and to destroy you; and ye shall be plucked from off the land whither thou goest in to possess it.
