Solomon
Proverbs 2:8ESV·traditional attribution

guarding the paths of justice and watching over the way of his saints.

Matthew Henry Presbyterian @wholebiblehenry

Job had asked, long before this, Where shall wisdom be found? Whence cometh wisdom? (Job 28:12, Job 28:20) and he had given this general answer (v. 23), God knoweth the place of it; but Solomon here goes further, and tells us both where we may find it and how we may get it. We are here told, I. What means we must use that we may obtain wisdom. 1.

Commenting on Proverbs 2:1-9

John Gill Reformed Baptist @doctorgill

He keepeth the paths of judgment,.... That is, the Lord keeps them; he does that which is just and right himself, in the course of his providence, and in the methods of his grace; and as he guides the feet of his people in the ways of righteousness and holiness, he keeps them there from turning out of them.

Jamieson-Fausset-Brown Reformed @jfbcommentary

keepeth . . . way--God defends the right way, and those in it. saints--objects of favor (compare Psa 4:3, &c.). He guides and guards them.
