Proverbs 18:15 The heart of the prudent gets knowledge; and the ear of the wise seeks knowledge. 

‘The prudent’ [Hebrew: ʿārūm] meaning sensible, discerning: actively pursues knowledge, it’s not passive. His heart (mind, will, and inner desire) is set on gaining insight, not just accumulating facts. The wise person is also described as someone who is always listening, always learning. His ear is attuned to truth, correction, and counsel.

Wisdom and prudence are not static traits; they are marked by a constant appetite for learning. The wise person is a lifelong student, both of God and of life.

“Give instruction to a wise man, and he will be yet wiser…” (9:9)
