Thou therefore, thy sons, and thy servants
Which were many, and whose numbers are after given:
shall till the land for him;
manure it, plough it, sow it, and reap it:
and thou shall bring in [the fruits];
the corn, and oil, and wine, the land produces:
that thy master's son may have food to eat;
meaning either Micha, the son of Mephibosheth, since Mephibosheth seems to be distinguished from him, and opposed to him in the next clause: and who would stand in no need of food from any other quarter, being a guest at the king's table continually; or else Mephibosheth, who by this means would have a sufficiency for his son and servants, and in which Ziba's family and servants would have a share:
but Mephibosheth thy master's son shall eat always at my table;
wherefore the land was to be tilled not for him personally, but for his family, and for what uses he should think fit to put the produce of it to:
now Ziba had fifteen sons and twenty servants:
who were enough to cultivate a considerable quantity of land.
