Job 31:17

Or have eaten my morsel myself alone -If I have not imparted what I had though ever so small, to others. This was in accordance with the Oriental laws of hospitality. It is regarded as a fixed law among the Arabians, that the guest shall always be helped first, and to that which is best; and no matter how needy the family may be, or how much distressed with hunger, the settled laws of hospitality demand that the stranger-guest shall have the first and best portion. Dr. Robinson, in his “Biblical Researches,” gives an amusing instance of the extent to which this law is carried, and the sternness with which it is executed among the Arabs.
