Jeremiah 15:18-19

18 Why is my pain perpetual, and my wound incurable, which refuses to be healed? will you be altogether to me as a liar, and as waters that fail?

19 Therefore thus said the LORD, If you return, then will I bring you again, and you shall stand before me: and if you take forth the precious from the vile, you shall be as my mouth: let them return to you; but return not you to them.
