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.  And I will make thee unto this people a fenced brasen wall: and they shall fight against thee, but they shall not prevail against thee: for I am with thee to save thee and to deliver thee, saith the LORD.  And I will deliver thee out of the hand of the wicked, and I will redeem thee out of the hand of the terrible.”

Jeremiah 15:19-21
