Proverbs 20:29

²⁷ The spirit of a man is the lamp of the LORD, searching out his inmost being.

²⁸ Loving devotion and faithfulness preserve a king; by these he maintains his throne.

The glory of young men is their strength, and gray hair is the splendor of the old.

³⁰ Lashes and wounds scour evil, and beatings cleanse the inmost parts.
