'Curse' in the Bible

When he turned around and looked at them, he cursed them in the name of the Lord. Then two female bears came out of the woods and tore to pieces forty-two of the boys.

No doubt the story has come to your ears of what the kings of Assyria have done to all lands, putting them to the curse; and will you be kept safe?

Because thine heart was tender, and thou hast humbled thyself before the LORD, when thou heardest what I spake against this place, and against the inhabitants thereof, that they should become a desolation and a curse, and hast rent thy clothes, and wept before me; I also have heard thee, saith the LORD.
