Solomon
Proverbs 20:7ESV·traditional attribution

The righteous who walks in his integrity— blessed are his children after him!

Matthew Henry Presbyterian @wholebiblehenry

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.

John Gill Reformed Baptist @doctorgill

The just man walketh in his integrity,.... This is the faithful and upright man, who is made righteous by the obedience of Christ; and walks by faith in him, and according to the truth of the Gospel; his children are blessed after him; with temporal blessings; and, walking in the same integrity as he does, they are blessed with spiritual blessings here, and eternal blessedness hereafter; see Psa 37:26.

Jamieson-Fausset-Brown Reformed @jfbcommentary

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