Leviticus 10:10 And that ye may put difference between holy and unholy, and between unclean and clean;

Jeremiah 15:19 ¶Therefore thus saith the LORD, If thou return, then will I bring thee again, and thou shalt stand before me: and if thou take forth the precious from the vile, thou shalt be as my mouth: let them return unto thee; but return not thou unto them.

2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:

Malachi 3:18 Then shall ye return, and discern between the righteous and the wicked, between him that serveth God and him that serveth him not.
