Ephesians 5:10-13 King James Version (KJV)
10 Proving what is acceptable unto the Lord.
11 And have no fellowship with the unfruitful works of darkness, but rather reprove them.
12 For it is a shame even to speak of those things which are done of them in secret.
13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light.
