Proverbs 4 : 23, 24, 25, 26, 27
Keep Thy heart with all diligence; for out of it are the issues of life.
Put away from thee a froward mouth, and perverse lips put far from thee.
Let thine eyes look right on, and let thine eyelids look straight before thee.
Ponder the path of thine feet, and let all thy ways be established.
Turn not the the right hand nor the the left: remove thy foot from evil.
( KJV )
