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. It is an observation of an Heathen poet (c), that good things befall the children of the godly, but not the children of the ungodly. (c) Theoerit. Idyll. 27. v. 32.
