'Destroy' in the Bible

And David saith, 'Jehovah, God of Israel, Thy servant hath certainly heard that Saul is seeking to come in unto Keilah, to destroy the city on mine account.

and, now, swear to me by Jehovah -- thou dost not cut off my seed after me, nor dost thou destroy my name from the house of my father.'

And David saith unto Abishai, 'Destroy him not; for who hath put forth his hand against the anointed of Jehovah, and been acquitted?'

And David saith unto Abner, 'Art not thou a man? and who is like thee in Israel? but why hast thou not watched over thy lord the king? for one of the people had come in to destroy the king, thy lord.
