23:18 Thou shalt not bring the {i} hire of a whore, or the price of a dog, into the house of the LORD thy God for any vow: for even both these [are] abomination unto the LORD thy God.
(i) Forbidding that any income gained from evil things should be applied to the service of God, Mic 2:7.
23:18 The hire of a whore - This is opposed to the practice of the Gentiles, who allowed both such persons and the oblations they made out of their infamous gains; and some of them kept lewd women, who prostituted themselves in the temples, to the honour of their false Gods, and offered part of their profit to them. Or the price of a dog - It seems to mean, of a whoremonger or sodomite. Such are called dogs, Rev 22:15. And it is not improbable they are called so here. From these God would not accept of any offering.
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.
