Numbers 7:1, 10-11, 84

When Moses finished setting up The Dwelling, he anointed it and consecrated it along with all that went with it. At the same time he anointed and consecrated the Altar and its accessories.

When the Altar was anointed, the leaders brought their offerings for its dedication and presented them before the Altar because GOD had instructed Moses, “Each day one leader is to present his offering for the dedication of the Altar.”

These were the dedication offerings of the leaders of Israel for the anointing of the Altar: twelve silver plates, twelve silver bowls, twelve gold vessels.
