Charles Ellicott Commentary Proverbs 24:14

"So shalt thou know wisdom to be unto thy soul; If thou hast found it, then shall there be a reward, And thy hope shall not be cut off." — Proverbs 24:14 (ASV)

So shall the knowledge of wisdom be unto thy soul. —Rather, Know (or understand) that wisdom is such (equally sweet and good) for your soul.

A reward. —Literally, a future. (Compare to Proverbs 23:18.)
