Charles Ellicott Commentary Proverbs 1:3

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

To receive the instruction of wisdom—To take in, or appropriate, the “discipline” which results in “prudence” (haskçl) or practical wisdom; so David behaved himself wisely (1 Samuel 18:5).

Equity—Literally, what is straight, so true, honest.
