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.
So, God says this: If you follow me, I'll bring you back and we'll stand together. If you separate the good from the bad, you'll be like my messenger. Let them come to you, but don't go to them.
