Jeremiah 6:27-30 NLT

“Jeremiah, I have made you a tester of metals, that you may determine the quality of my people. They are the worst kind of rebel, full of slander. They are as hard as bronze and iron, and they lead others into corruption. The bellows fiercely fan the flames to burn out the corruption. But it does not purify them, for the wickedness remains. I will label them ‘Rejected Silver,’ for I, the LORD, am discarding them.”
