Psalm 37/Notes/Lexical.v. 30.423011
From Psalms: Layer by Layer
The abstract nouns wisdom and justice are metonymic for "that which is wise" and "that which is just" (cf. NIV: "what is just"). Words that are just are words that conform to YHWH's law, i.e., they are characterized by truth, honesty and love for one's neighbor.
