'Curse' in the Bible

'Curse Meroz,' says the angel of Yahweh; 'curse bitterly its inhabitants, because they did not come to the help of Yahweh, to the help of Yahweh against the mighty.'

And God also repaid all the wickedness of the men of Shechem on their heads, and the curse of Jotham son of Jerub-Baal fell on them.

And he said to his mother, "The eleven hundred [pieces] of silver that were taken from you, and about which you also pronounced a curse {in my hearing}, are with me; I took it." And his mother said, "Blessed be my son by Yahweh."
