Yirmeyah 6:28-30

Orthodox Jewish Bible

²⁸ They are all maximum rebels, going about as rachil (talebearers, slanderers); they are nechoshet and barzel; they are all corrupt.

²⁹ The bellows blow, the oferet (lead) is consumed by the eish; the smelter’s refining is in vain; for the ra’im are not drawn off.

³⁰ Nimas kesef (reprobate silver, rejected silver) shall men call them, because Hashem hath rejected them.
