'Curse' in the Bible

If ye will not hear, and if ye will not lay it to heart, to give glory unto my name, saith Jehovah of hosts, then will I send the curse upon you, and I will curse your blessings; yea, I have cursed them already, because ye do not lay it to heart.

Ye are cursed with the curse; for ye rob me, even this whole nation.

And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers; lest I come and smite the earth with a curse.
