Numbers 31:50-52
31:50 So we have brought as an offering for the Lord what each man found: gold ornaments, armlets, bracelets, signet rings, earrings, and necklaces, to make atonement for ourselves before the Lord.”
31:51 Moses and Eleazar the priest took the gold from them, all of it in the form of ornaments.
31:52 All the gold of the offering they offered up to the Lord from the commanders of thousands and the commanders of hundreds weighed 16,750 shekels.
