Proverbs 4:20-24

My son, give attention to my words; Incline your ear to my sayings. Do not let them depart from your sight; Keep them in the midst of your heart. For they are life to those who find them And health to all their body. Watch over your heart with all diligence, For from it flow the springs of life. Put away from you a deceitful mouth And put devious speech far from you.
