'Cursing' in the Bible

Let peoples serve you, and nations bow down to you; Be lord of your brothers, and may the sons of your mother bow down to you. Cursed be those cursing you, and blessed be those blessing you."

King David came up to Bahurim and suddenly a man from there [was] coming out from the family of the house of Saul, and his name [was] Shimei the son of Gera. {He was cursing as he came out}.

Shimei said while cursing him, "Go out, go out, [you] {man of bloodshed}, [you] {man of wickedness}.

Then David and his men went on the road, with Shimei going on the side of the hill beside him, {cursing as he went}. He threw stones beside him and threw dust in the air.

His mouth is filled with cursing, with deceits and oppression; under his tongue are trouble and evil.

Because he loved cursing, let it come [upon] him. Because he did not delight in blessing, let it be far from him.

Woe to me, my mother, that you gave birth to me, a man of contention and quarreling {to the whole land}. I have not lent out and {I have not borrowed}. All of them [are] cursing me.

whose mouth is full of cursing and bitterness.

From the same mouth come blessing and cursing. My brothers, these [things] ought not to be so!
