Prov 4:20-23 My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of thine heart. For they are life unto those that find them, and health to all their flesh. Keep thy heart with all diligence; for out of it are the issues of life.
(KJV)
Prov 4:20-22 Listen, son of mine, to what I say. Listen carefully. Keep these thoughts ever in mind; let them penetrate deep within your heart, for they will mean real life for you and radiant health.
(TLB)
Prov 4:20-22 My son, attend to my words; consent and submit to my sayings. Let them not depart from your sight; keep them in the center of your heart. For they are life to those who find them, healing and health to all their flesh. (AMP)
