Proverbs 4:20-23

20 My son, attend to my words; incline thine ear unto my sayings.
21 Let them not depart from thine eyes; keep them in the midst of thine heart.
22 For they are life unto those that find them, and health[a] to all their flesh.
23 Keep thy heart with all diligence; for out of it are the issues of life.
