Jeremiah 15:18-20

Why is my pain perpetual, and my wound incurable, which refuseth to be healed? wilt thou indeed be unto me as a deceitful brook, as waters that fail? Therefore thus saith Jehovah, If thou return, then will I bring thee again, that thou mayest stand before me; and if thou take forth the precious from the vile, thou shalt be as my mouth: they shall return unto thee, but thou shalt not return unto them. And I will make thee unto this people a fortified brazen 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 Jehovah.
