These were the gifts from the leaders of Israel for the dedication of the altar when it was anointed: 12 silver plates, 12 silver bowls, and 12 gold dishes.
When Moses finished setting up the tent, he anointed it and dedicated it and all the furnishings. He also anointed and dedicated the altar and all the utensils.
Each silver plate weighed 3¼ pounds, and each bowl weighed 1¾ pounds. Together all the silver dishes weighed 60 pounds, using the standard weight of the holy place.
