Verse 21. - Thou shalt not glean it afterward; literally, Thou shalt not glean after thee, i.e. after thou hast reaped and gathered for thyself. It is still the custom among the Arabs for the poor to be allowed to gather the berries that may be left on the olive trees after they have been beaten and the main produce carried off by the owner. All the injunctions in this section are adapted to preserve relations of brotherliness and love among the people of the Lord.

24:14-22 It is not hard to prove that purity, piety, justice, mercy, fair conduct, kindness to the poor and destitute, consideration for them, and generosity of spirit, are pleasing to God, and becoming in his redeemed people. The difficulty is to attend to them in our daily walk and conversation.When thou gatherest the grapes of thy vineyard,.... Which was done much about the same time that the olives were gathered, and both after wheat harvest, about the latter end of June, or beginning of July; for they were more forward in those hot countries:

thou shall not glean it afterwards; go over the vines a second time, to pick off every berry or bunch that escaped them at first gathering:

it shall be for the stranger, for the fatherless, and for the widow; as the forgotten sheaf, and the olive berries left; these are all supposed to be poor persons, otherwise no doubt there were strangers, and fatherless persons, and widows, in good circumstances; who, as they needed not, so neither would give themselves the trouble, but think it beneath them to go into fields, oliveyards, and vineyards, to gather what was left by the owners. These laws were made in favour of the poor, that mercy and kindness might be showed to them, and that they might have a taste of all the fruits of the earth.
