Proverbs 4:20-23 New Revised Standard Version (NRSV)
20 My child, be attentive to my words;
incline your ear to my sayings.
21 Do not let them escape from your sight;
keep them within your heart.
22 For they are life to those who find them,
and healing to all their flesh.
23 Keep your heart with all vigilance,
for from it flow the springs of life.
