Numbers 7:1-2

1On the day that Moses had finished setting up the tabernacle and had anointed and consecrated it and all its furniture, and the altar and all its utensils; he also anointed them and consecrated them [for holy use].

2Then the leaders of Israel, the heads of their fathers’ households, made offerings. (These were the leaders of the tribes; they were the ones who were over the men who were numbered.)
