Thou therefore, and thy sons, and thy servants, shall till the land for him, and thou shalt bring in the fruits, that thy master's son may have food to eat: but Mephibosheth thy master's son shall eat bread alway at my table. Now Ziba had fifteen sons and twenty servants. Thou therefore, and thy sons - shall till the land - It seems that Ziba and his family had the care of the whole estate, and cultivated it at their own expense, yielding the half of the produce to the family of Mephibosheth. Ziba was properly the hind, whose duty and interest it was to take proper care of the ground, for the better it was cultivated the more it produced; and his half would consequently be the greater.
