⁵ Deep waters are like purpose in the heart^[a] of a man,
    and a man of understanding will draw it^[b] out.
⁶ Many a person will proclaim his loyalty for himself,
    but a man who is trustworthy, who can find?

⁹ Who will say “I have made my heart^[a] clean;
    I am pure from my sin”?

²⁹ The glory of young men is their strength,^[a]
    but the beauty of the aged is gray hair.
