Numbers 31:50-54

So we are presenting the items of gold we captured as an offering to the LORD from our share of the plunder—armbands, bracelets, rings, earrings, and necklaces. This will purify our lives before the LORD and make us right with him.” So Moses and Eleazar the priest received the gold from all the military commanders—all kinds of jewelry and crafted objects. In all, the gold that the generals and captains presented as a gift to the LORD weighed about 420 pounds. All the fighting men had taken some of the plunder for themselves. So Moses and Eleazar the priest accepted the gifts from the generals and captains and brought the gold to the Tabernacle as a reminder to the LORD that the people of Israel belong to him.
