'Curse' in the Bible

‘Curse Meroz,’ said the angel of the Lord,‘Utterly curse its inhabitants;Because they did not come to the help of the Lord,To the help of the Lord against the warriors.’

Also God returned all the wickedness of the men of Shechem on their heads, and the curse of Jotham the son of Jerubbaal came upon them.

He said to his mother, “The eleven hundred pieces of silver which were taken from you, about which you uttered a curse in my hearing, behold, the silver is with me; I took it.” And his mother said, “Blessed be my son by the Lord.”
