Jeremiah 6:27 MSG

[27] God gave me this task: “I have made you the examiner of my people, to examine and weigh their lives. They’re a thickheaded, hard-nosed bunch, rotten to the core, the lot of them. Refining fires are cranked up to white heat, but the ore stays a lump, unchanged. It’s useless to keep trying any longer. Nothing can refine evil out of them. Men will give up and call them ‘slag,’ thrown on the slag heap by me, their God.”
