'Curse' in the Bible

And turning back, he saw them, and put a curse on them in the name of the Lord. And two she-bears came out of the wood and put forty-two of the children to death.

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 your heart was soft, and you made yourself low before me, when you had word of what I said against this place and its people, that they would become a waste and a curse, and you gave signs of grief, weeping before me: truly, I have given ear to you, says the Lord.
