Proverbs 20:7 New English Translation

⁷The righteous person^[a] behaves in integrity;^[b]
blessed are his children after him.^[c]

Proverbs 20:7 sn Two terms describe the subject of this proverb: “righteous” and “integrity.” The first describes the person as a member of the covenant community who strives to live according to God’s standards; the second emphasizes that his lifestyle is blameless.
Proverbs 20:7 tn Heb “walks in his integrity” (so NASB); cf. NIV “leads a blameless life.” The Hitpael participle of הָלַךְ (halakh) means “to walk about; to walk to and fro.” The idiom of walking representing living is intensified here in this stem. This verbal stem is used in scripture to describe people “walking with” God.
Proverbs 20:7 sn The nature and the actions of parents have an effect on children (e.g., Exod 20:4-6); if the parents are righteous, the children will enjoy a blessing—the respect and the happiness which the parent reflects on them.
