'Guarded' in the Bible

David had just said, “I guarded everything that belonged to this man in the wilderness for nothing. He was not missing anything, yet he paid me back evil for good.

And David said to Abner, Art not thou a man? and who is like to thee in Israel? and why hast thou not guarded thy lord the king? for one of the people came in to destroy the king thy lord.

This thing is not good which thou hast done. As Jehovah liveth, ye are worthy to die, because ye have not guarded your master, Jehovah's anointed. And now see where the king's spear is, and the cruse of water that was at his head.

David said, "No, you won't do this, my brothers, with what the LORD has given us. He guarded us and gave the raiding party that came against us into our hand.
