Verse 1-8 — We ought to value the privileges of God's people, both for ourselves and for our children, above all other advantages. No personal blemishes, no crimes of our forefathers, no difference of nation, shuts us out under the Christian dispensation. But an unsound heart will deprive us of blessings; and a bad example, or an unsuitable marriage, may shut our children from them.
Verse 9-14 — The camp of the Lord must have nothing offensive in it. If there must be this care taken to preserve the body clean, much more should we be careful to keep the mind pure.
Verse 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.
