Laws of Human Relations

15 "If slaves should escape from their masters and take refuge with you, you must not hand them over to their masters. 16 Let them live among you in any town they choose, and do not oppress them. 17 "No Israelite, whether man or woman, may become a temple prostitute. 18 When you are bringing an offering to fulfill a vow, you must not bring to the house of the Lord your God any offering from the earnings of a prostitute, whether a man or a woman, for both are detestable to the Lord your God. 19 "Do not charge interest on the loans you make to a fellow Israelite, whether you loan money, or food, or anything else. 20 You may charge interest to foreigners, but you may not charge interest to Israelites, so that the Lord your God may bless you in everything you do in the land you are about to enter and occupy. 21 "When you make a vow to the Lord your God, be prompt in fulfilling whatever you promised him. For the Lord your God demands that you promptly fulfill all your vows, or you will be guilty of sin. 22 However, it is not a sin to refrain from making a vow. 23 But once you have voluntarily made a vow, be careful to fulfill your promise to the Lord your God. 24 "When you enter your neighbor's vineyard, you may eat your fill of grapes, but you must not carry any away in a basket. 25 And when you enter your neighbor's field of grain, you may pluck the heads of grain with your hand, but you must not harvest it with a sickle.

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.
