'Belong' in the Bible

So should I take my bread and my water and my meat that I have slaughtered for my shearers, and give it to men when I do not know where they are from?”

May God do so to the enemies of David, and more also, if by morning I leave [alive] even one male of any who belong to him.”

David said to him, “To whom do you belong, and where are you from?” He said, “I am a young man from Egypt, a servant of an Amalekite; and my master abandoned me [as useless] when I fell sick three days ago.
