19 When you harvest your grain and forget a sheaf back in the field, don't go back and get it; leave it for the foreigner, the orphan, and the widow so that God, your God, will bless you in all your work. 20 When you shake the olives off your trees, don't go back over the branches and strip them bare - what's left is for the foreigner, the orphan, and the widow. 21 And when you cut the grapes in your vineyard, don't take every last grape - leave a few for the foreigner, the orphan, and the widow.

Matthew Henry's Commentary on Deuteronomy 24:19-21

Commentary on Deuteronomy 24:14-22

(Read Deuteronomy 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.
