⁵ The purpose in a man’s mind is like deep water,
    but a man of understanding will draw it out.
⁶ Many a man proclaims his own loyalty,
    but a faithful man who can find?

⁹ Who can say, “I have made my heart clean;
    I am pure from my sin”?

²⁹ The glory of young men is their strength,
    but the beauty of old men is their gray hair.
