'Curse' in the Bible

If ye hearken not, and if ye lay it not to heart, To give honour to My name, said Jehovah of Hosts, I have sent against you the curse, And I have cursed your blessings, Yea, I have also cursed it, Because ye are not laying it to heart.

With a curse ye are cursed! And Me ye are deceiving -- this nation -- all of it.
