'Curse' in the Bible

Then Abishai son of Zeruiah said to the king, "Why should this dead dog curse my lord the king? Let me go over and cut off his head!"

But the king said, "What do we have in common, you sons of Zeruiah? If he curses because the Lord has said to him, 'Curse David!', who can say to him, 'Why have you done this?'"

Then David said to Abishai and to all his servants, "My own son, my very own flesh and blood, is trying to take my life. So also now this Benjaminite! Leave him alone so that he can curse, for the Lord has spoken to him.

Perhaps the Lord will notice my affliction and this day grant me good in place of his curse."

The men of Israel replied to the men of Judah, "We have ten shares in the king, and we have a greater claim on David than you do! Why do you want to curse us? Weren't we the first to suggest bringing back our king?" But the comments of the men of Judah were more severe than those of the men of Israel.
