'Cursed' in the Bible

"Behold, there is with you 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 swore to him by Yahweh, saying, 'I will not put you to death with the sword.'

Set two men, base fellows, before him, and let them testify against him, saying, 'You cursed God and the king!' Then carry him out, and stone him to death."

The two men, the base fellows, came in and sat before him. The base fellows testified against him, even against Naboth, in the presence of the people, saying, "Naboth cursed God and the king!" Then they carried him out of the city, and stoned him to death with stones.
