¹⁰ The heart knows its own bitterness—
    an outsider cannot share in its joy.

¹³ Even in laughter there may be heartache,
    and at the end of joy there may be grief.

¹³ A happy heart enlightens the face,
    but a sad heart reflects a broken spirit.

²² A joyful heart is good medicine,
    but a broken spirit drains one’s strength.^[a]

¹⁴ A man’s spirit can sustain him during his illness,
    but who can bear a crushed spirit?

²⁰ Taking your coat off when it’s cold
    or pouring vinegar on soda—
        that’s what singing songs does to a heavy heart.

¹¹ Be wise, my son, and make me happy,
    so I can reply to anyone who insults me.
