Proverbs 18:15
The heart of the prudent getteth knowledge; and the ear of the wise seeketh knowledge.
The heart of the prudent getteth knowledge,.... More knowledge; for he must have some, and a considerable share, to be denominated "prudent", whether in things natural, civil, or spiritual: and such will be heartily desirous of more, and make use of all means to attain it, by which they do come at a large share of it;
and the ear of the wise seeketh knowledge; a wise man seeks to get it by hearing; he listens to what others say, and especially such that are wiser and more knowing than himself: so such as are wise to salvation, as they desire to know more of Christ and of divine things, and make use of all means for that purpose; among the rest, hearken to what Christians, of a superior class to themselves, drop in private conversation; and particularly they constantly attend to the ministry of the word; and thus seeking it, they find an increase of it.
