עפרת עפרת , Exod. xv, 10; Num. xxx i, 22; Job xix, 24; Jer. vi, 29; Ezek. xxii, 18; xxvii, 12; Zech. v, 7, 8; a mineral of a bluish white colour. It is the softest next to gold, but has no great tenacity, and is not in the least sonorous. It is mentioned with five other species of metal, Num. xxx i, 22; and there is no doubt but that this is the meaning of the word; so the Septuagint render it throughout, μόλιϐδος or μόλιϐος.
