19 "When you are harvesting your crops and forget to bring in a bundle of grain from your field, don't go back to get it. Leave it for the foreigners, orphans, and widows. Then the Lord your God will bless you in all you do. 20 When you beat the olives from your olive trees, don't go over the boughs twice. Leave the remaining olives for the foreigners, orphans, and widows. 21 When you gather the grapes in your vineyard, don't glean the vines after they are picked. Leave the remaining grapes for the foreigners, orphans, and widows.

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.
