The heart of the prudent getteth knowledge; and the ear of the wise seeketh knowledge.
– Proverbs 18:15
The word for knowledge means understanding, or learning. Getting and seeking knowledge means it can be increased. Our understanding and learning can, and should, grow. The proverb’s punch is in the seeming paradox. The prudent and the wise are seeking knowledge. The modern utilitarian mind wonders why they would do that if they are already wise and prudent. The word for prudent has to do with separating, or making distinctions. The word for wise means shrewd, skillful, or crafty. The first means having discernment—the ability to sort out the things learned. The second means being able to figure things out and make plans. They are continually looking and listening to acquire learning (Proverbs 1:5; 9:9; 15:14). Fools are only interested in what they think they need to know (Proverbs 14:6; 18:2; 26:12).
