Laws of Human Relations

15 "You shall not give back to his master the slave who has escaped from his master to you. 16 He may dwell with you in your midst, in the place which he chooses within one of your gates, where it seems best to him; you shall not oppress him. 17 "There shall be no ritual harlot of the daughters of Israel, or a perverted one of the sons of Israel. 18 You shall not bring the wages of a harlot or the price of a dog to the house of the Lord your God for any vowed offering, for both of these are an abomination to the Lord your God. 19 "You shall not charge interest to your brother--interest on money or food or anything that is lent out at interest 20 To a foreigner you may charge interest, but to your brother you shall not charge interest, that the Lord your God may bless you in all to which you set your hand in the land which you are entering to possess. 21 "When you make a vow to the Lord your God, you shall not delay to pay it; for the Lord your God will surely require it of you, and it would be sin to you 22 But if you abstain from vowing, it shall not be sin to you. 23 That which has gone from your lips you shall keep and perform, for you voluntarily vowed to the Lord your God what you have promised with your mouth. 24 "When you come into your neighbor's vineyard, you may eat your fill of grapes at your pleasure, but you shall not put any in your container. 25 When you come into your neighbor's standing grain, you may pluck the heads with your hand, but you shall not use a sickle on your neighbor's standing grain.

Commentary on Deuteronomy 23:15-25

(Read Deuteronomy 23:15-25)

It is honourable to shelter and protect the weak, provided they are not wicked. Proselytes and converts to the truth, should be treated with particular tenderness, that they may have no temptation to return to the world. We cannot honour God with our substance, unless it be honestly and honourably come by. It must not only be considered what we give, but how we got it. Where the borrower gets, or hopes to get, it is just that the lender should share the gain; but to him that borrows for necessary food, pity must be showed. That which is gone out of thy lips, as a solemn and deliberate vow, must not be recalled, but thou shalt keep and perform it punctually and fully. They were allowed to pluck and eat of the corn or grapes that grew by the road side; only they must not carry any away. This law intimated what great plenty of corn and wine they should have in Canaan. It provided for the support of poor travellers, and teaches us to be kind to such, teaches us to be ready to distribute, and not to think every thing lost that is given away. Yet it forbids us to abuse the kindness of friends, or to take advantage of what is allowed. Faithfulness to their engagements should mark the people of God; and they should never encroach upon others.
