Jeremiah 6:26-30

O daughter of my people, gird thee with sackcloth, and wallow thyself in ashes: make thee mourning, as for an only son, most bitter lamentation: for the spoiler shall suddenly come upon us.

I have set thee for a tower and a fortress among my people, that thou mayest know and try their way.

They are all grievous revolters, walking with slanders: they are brass and iron; they are all corrupters.

The bellows are burned, the lead is consumed of the fire; the founder melteth in vain: for the wicked are not plucked away.

Reprobate silver shall men call them, because the LORD hath rejected them.
