John Gill Commentary Proverbs 13:22

"A good man leaveth an inheritance to his children`s children; And the wealth of the sinner is laid up for the righteous." — Proverbs 13:22 (ASV)

A good [man] leaveth an inheritance to his children's
children
He not only has a sufficiency for the present support of himself and family; but is so prospered and succeeded, as to leave an inheritance after him; and which is continued to and enjoyed, not only by his immediate offspring, but theirs also; for being got honestly, it wears well; see (Proverbs 13:11) ;

and the wealth of the sinner [is] laid up for the just ;
the riches which wicked men get are laid up in the purposes of God for good men; and in his providence they are translated from the one to the other: so the riches of the Egyptians were designed for the Israelites, and by the providence of God were put into their hands; see (Job 27:16Job 27:17) (Proverbs 28:8) (Ecclesiastes 2:26) .
