Jeremiah 6:30

Jer 6:30 Reprobate silver shall [men] call them, because the LORD hath rejected them.

Ver. 30. Reprobate a silver shall men call them.] Dross and refuse, rather than pure metal; "silver" they would seem to be, but their hypocrisy shall be made known to all men, who shall count them and call them "reprobate," because impurgabiles and inexpiabiles, uncounsellable and incorrigible; b a sure sign of reprobation, as Aquinas noteth from Hebrews 6:7-8 .

For the Lord hath rejected them. ] As refuse and counterfeit, such as will not pass in payment. c Hence they are to be cast into Babylon’s iron furnace ( quasi antro Aetnaeo et Cyclopico adhuc decoquendi ), a type of that eternal fire of hell prepared of old for the devil and reprobates.
