30. The light in the eyes [of him whose heart is joyful] rejoices the hearts of others, and good news nourishes the bones.
31. The ear that listens to the reproof [that leads to or gives] life will remain among the wise.
32. He who refuses and ignores instruction and correction despises himself, but he who heeds reproof gets understanding.
33. The reverent and worshipful fear of the Lord brings instruction in Wisdom, and humility comes before honor.
