Jeremiah 6:27-30

27“I have 1made you an assayer and an examiner among My people, So that you may know and put their way to the test.”28All of them are stubbornly rebellious, 2Going about as a slanderer; They are 3bronze and iron. They are, all of them, corrupt.29The bellows blow fiercely, The lead is consumed by the fire; In vain the refining goes on, But the 4wicked are not 5separated.306They call them rejected silver, Because the 7Lord has rejected them.
