Solomon
Proverbs 1:3ESV·traditional attribution

to receive instruction in wise dealing, in righteousness, justice, and equity;

Matthew Henry Presbyterian @wholebiblehenry

We have here an introduction to this book, which some think was prefixed by the collector and publisher, as Ezra; but it is rather supposed to have been penned by Solomon himself, who, in the beginning of his book, proposes his end in writing it, that he might keep to his business, and closely pursue that end. We are here told, I. Who wrote these wise sayings, Pro 1:1.

Commenting on Proverbs 1:1-6

John Gill Reformed Baptist @doctorgill

To receive the instruction of wisdom,.... Or "prudence" (h); of wise and prudent men; and especially of Christ himself, who bears those names, whose instructions this book is full of; and the design of which is to engage the attention of men to them, and prevail upon them to receive them, and act conformably to them.

Jamieson-Fausset-Brown Reformed @jfbcommentary

To receive . . . of wisdom--For receiving that discipline which discretion imparts. The Hebrew for "wisdom" differs from that of Pro 1:2, and denotes rather discreet counsel. Compare the opposite traits of the fool (Pro 16:22). justice . . . equity--all the attributes of one upright in all his relations to God and man.
