Laws of Human Relations

15 Slaves who have escaped to you from their owners shall not be given back to them. 16 They shall reside with you, in your midst, in any place they choose in any one of your towns, wherever they please; you shall not oppress them. 17 None of the daughters of Israel shall be a temple prostitute; none of the sons of Israel shall be a temple prostitute. 18 You shall not bring the fee of a prostitute or the wages of a male prostitute into the house of the Lord your God in payment for any vow, for both of these are abhorrent to the Lord your God. 19 You shall not charge interest on loans to another Israelite, interest on money, interest on provisions, interest on anything that is lent 20 On loans to a foreigner you may charge interest, but on loans to another Israelite you may not charge interest, so that the Lord your God may bless you in all your undertakings in the land that you are about to enter and possess. 21 If you make a vow to the Lord your God, do not postpone fulfilling it; for the Lord your God will surely require it of you, and you would incur guilt 22 But if you refrain from vowing, you will not incur guilt. 23 Whatever your lips utter you must diligently perform, just as you have freely vowed to the Lord your God with your own mouth. 24 If you go into your neighbor's vineyard, you may eat your fill of grapes, as many as you wish, but you shall not put any in a container. 25 If you go into your neighbor's standing grain, you may pluck the ears with your hand, but you shall not put a sickle to 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.
