Charles Ellicott Commentary Proverbs 19:8

"He that getteth wisdom loveth his own soul: He that keepeth understanding shall find good." — Proverbs 19:8 (ASV)

He that getteth wisdom.— Literally, heart. For that “wisdom,” or “knowledge,” that begins with the “fear of the Lord” (see above on Proverbs 1:7), and ends with loving Him, is not a matter of intellect only, but of the heart also—i.e., the will and affections.
