The just man walketh in his integrity: his children are blessed after him.

Jamieson-Fausset-Brown Bible Commentary

7. The conduct of good men proclaims their sound principles. God's covenant and their good example secure blessing to their children (Pr 4:26; Ps 112:1, 2).

Matthew Henry's Concise Commentary

20:7. A good man is not liable to uneasiness in contriving what he shall do, or in reflecting on what he has done, as those who walk in deceit. And his family fare better for his sake. 8. If great men are good men, they may do much good, and prevent very much evil. 9. Some can say, Through grace, we are cleaner than we have been; but it was the work of the Holy Spirit. 10. See the various deceits men use, of which the love of money is the root. The Lord will not bless what is thus gotten. 11. Parents should observe their children, that they may manage them accordingly. 12. All our powers and faculties are from God, and are to be employed for him. 13. Those that indulge themselves, may expect to want necessaries, which should have been gotten by honest labour. 14. Men use arts to get a good bargain, and to buy cheap; whereas a man ought to be ashamed of a fraud and a lie. 15. He that prefers true knowledge to riches, follows the ways of religion and happiness. If we really believed this truth, the word of God would be valued as it deserves, and the world would lose its tempting influence. 16. Those ruin themselves who entangle themselves in rash suretiship. Also those who are in league with abandoned women. Place no confidence in either. 17. Wealth gotten by fraud may be sweet, for the carnal mind takes pleasure in the success of wicked devices; but it will be bitter in the reflection. 18. Especially we need advice in spiritual warfare. The word and Spirit of God are the best counsellors in every point. 19. Those dearly buy their own praise, who put confidence in a man because he speaks fairly. 20. An undutiful child will become very miserable. Never let him expect any peace or comfort. 21. An estate suddenly raised, is often as suddenly ruined. 22. Wait on the Lord, attend his pleasure, and he will protect thee.

Matthew Henry's Whole Bible Commentary

Verse 7

It is here observed to the honour of a good man, 1. That he does well for himself. He has a certain rule, which with an even steady hand he governs himself by: He walks in his integrity; he keeps good conscience, and he has the comfort of it, for it is his rejoicing. He is not liable to those uneasinesses, either in contriving what he shall do or reflecting on what he has done, which those are liable to that walk in deceit. 2. That he does well for his family: His children are blessed after him, and fare the better for his sake. God has mercy in store for the seed of the faithful.
