Proverbs 23:4 - Albert Barnes' Notes on the Bible

Cease from thine own wisdom - i. e., “Cease from the use of what is in itself most excellent, if it only serves to seek after wealth, and so ministers to evil.” There is no special contrast between “thine own wisdom” and that given from above, though it is of course implied that in ceasing from his own prudence the man is on the way to attain a higher wisdom.
