'Curse' in the Bible

And, behold, there is with thee Shimei the son of Gera, the Benjamite, of Bahurim, who cursed me with a grievous curse in the day when I went to Mahanaim; but he came down to meet me at the Jordan, and I sware to him by Jehovah, saying, I will not put thee to death with the sword.

and set two men, base fellows, before him, and let them bear witness against him, saying, Thou didst curse God and the king. And then carry him out, and stone him to death.

And the two men, the base fellows, came in and sat before him: and the base fellows bare witness against him, even against Naboth, in the presence of the people, saying, Naboth did curse God and the king. Then they carried him forth out of the city, and stoned him to death with stones.
