Jeremiah 6:27-30 - Jeremiah Appointed As An Examiner

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.
