Numbers 7:1, 10, 84

Now it came to pass, when Moses had finished setting up the tabernacle, that he anointed it and consecrated it and all its furnishings, and the altar and all its utensils; so he anointed them and consecrated them.

Now the leaders offered the dedication offering for the altar when it was anointed; so the leaders offered their offering before the altar.

This was the dedication offering for the altar from the leaders of Israel, when it was anointed: twelve silver platters, twelve silver bowls, and twelve gold pans.
