Proverbs 16:20-

Yes, insight is “a well of life” to those who have it. But what about the foolish? They ‘despise wisdom and discipline.’ (Proverbs 1:7) What results do they reap by rejecting discipline from Jehovah? As noted above, Solomon says: “The discipline of the foolish ones is foolishness.” (Proverbs 16:22) They receive further discipline, often in the form of severe chastisement. The foolish may also bring upon themselves hardship, shame, disease, and even untimely death.
