Numbers 7:10

Now it happened on the day that Moses had finished setting up the tabernacle, that he anointed it and set it apart as holy with all its furnishings and the altar and all its utensils; he anointed them and set them apart as holy.

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

and all the oxen for the sacrifice of peace offerings 24 bulls, all the rams 60, the male goats 60, the male lambs one year old 60. This was the dedication offering for the altar after it was anointed.
