Numbers 7:1-5

On 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]. Then 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.) They brought their offering before the LORD, six covered carts and twelve oxen; a cart for each two of the leaders and an ox for each one; and they presented them before the tabernacle. Then the LORD spoke to Moses, saying, “Accept these things from them, so that they may be used in the service of the Tent of Meeting (tabernacle), and give them to the Levites, to each man according to his service.”
