Jeremiah 15:21 Meaning

19Therefore 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.

20And 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.

21And I will deliver thee out of the hand of the wicked, and I will redeem thee out of the hand of the terrible.
