'Watched' in the Bible

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.

Not good is this thing which thou hast done; Jehovah liveth, but ye are sons of death, in that ye have not watched over your lord, over the anointed of Jehovah; and now, see where the king's spear is, and the cruse of water which is at his bolster.'
