Ecclesiasticus
King James Version (KJV)

Now viewing scripture range from the book of Ecclesiasticus chapter 6:13 through chapter 6:16...
13 Separate thyself from thine enemies, and take heed of thy friends.
14 A faithfull friend is a strong defence: and he that hath found such an one hath found a treasure.
15 Nothing doth countervail a faithful friend, and his excellency is invaluable.
16 A faithful friend is the medicine of life; and they that fear the Lord shall find him.
