Albert Barnes Commentary Proverbs 1:3

"To receive instruction in wise dealing, In righteousness and justice and equity;" — Proverbs 1:3 (ASV)

Wisdom - Not the same word as in (Proverbs 1:2); better, perhaps, thoughtfulness.

Justice - Rather, righteousness. The word in the Hebrew includes the ideas of truth and beneficence as well as “justice.”

Judgment - The teaching of the Proverbs is to lead us to pass a right sentence upon human actions, whether our own or another’s.

Equity - In the Hebrew (see the margin) the plural is used, and expresses the many varying forms and phases of the one pervading principle.
