³⁰ A peaceful heart leads to a healthy body;
    jealousy is like cancer in the bones.

²² A cheerful heart is good medicine,
    but a broken spirit saps a person’s strength.

⁴ A worthy wife is a crown for her husband,
    but a disgraceful woman is like cancer in his bones.

⁸ Then you will have healing for your body
    and strength for your bones.

²³ Guard your heart above all else,
    for it determines the course of your life.

¹⁰ The wicked will see this and be infuriated.
    They will grind their teeth in anger;
    they will slink away, their hopes thwarted.
