Proverbs
King James Version (KJV)

Now viewing scripture range from the book of Proverbs chapter 4:21 through chapter 4:24...
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 to all their flesh.
23 Keep thy heart with all diligence; for out of it are the issues of life.
24 Put away from thee a froward mouth, and perverse lips put far from thee.
