Proverbs 4:20-24

New International Version

²⁰ My son,^(A) pay attention to what I say;
    turn your ear to my words.^(B)
21 Do not let them out of your sight,^(C)
    keep them within your heart;
²² for they are life to those who find them
    and health to one’s whole body.^(D)
23 Above all else, guard^(E) your heart,
    for everything you do flows from it.^(F)
24 Keep your mouth free of perversity;
    keep corrupt talk far from your lips.
