Jeremiah 6:26-30 New American Standard Bible (NASB)

26. O daughter of my people, put on sackcloth And roll in ashes; Mourn as for an only son, A lamentation most bitter. For suddenly the destroyer Will come upon us.

27. "I have made you an assayer and a tester among My people, That you may know and assay their way."

28. All of them are stubbornly rebellious, Going about as a talebearer. They are bronze and iron; They, all of them, are corrupt.

29. The bellows blow fiercely, The lead is consumed by the fire; In vain the refining goes on, But the wicked are not separated.

30. They call them rejected silver, Because the Lord has rejected them.
