Jeremiah 15:18-19

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.
