Proverbs 13:22

See here, 1. How a good man's estate lasts: He leaves an inheritance to his children's children. It is part of his praise that he is thoughtful for posterity, that he does not lay all out upon himself, but is in care to do well for those that come after him, not by withholding more than is meet, but by a prudent and decent frugality. He trains up his children to this, that they may leave it to their children; and especially he is careful, both by justice and charity, to obtain the blessing of God upon what he has, and to entail that blessing upon his children, without which the greatest industry and frugality will be in vain: A good man, by being good and doing good, by honouring the Lord with his substance and spending it in his service, secures it to his posterity; or, if he should not leave them much of this world's goods, his prayers, his instructions, his good example, will be the best entail, and the promises of the covenant will be an inheritance to his children's children, Psa 103:17. 2. How it increases by the accession of the wealth of the sinner to it, for that is laid up for the just.

wealth . . . just--While good men's estates remain in their families, God so orders that the gains of sinners enure to the just (compare Pro 28:8; Psa 37:18, Psa 37:22, Psa 37:26, &c.).
