'Curse' in the Bible

Curse ye Meroz, said the angel of Jehovah. Curse ye bitterly the inhabitants thereof, Because they came not to the help of Jehovah, To the help of Jehovah against the mighty.

and all the wickedness of the men of Shechem did God requite upon their heads: and upon them came the curse of Jotham the son of Jerubbaal.

And he said unto his mother, The eleven hundred pieces of silver that were taken from thee, about which thou didst utter a curse, and didst also speak it in mine ears, behold, the silver is with me; I took it. And his mother said, Blessed be my son of Jehovah.
