Then the leaders of Israel, the heads of their fathers’ houses, who were the leaders of the tribes and over those who were numbered, made an offering.And they brought their offering before the Lord, six covered carts and twelve oxen, a cart for every two of the leaders, and for each one an ox; and they presented them before the tabernacle.Then the Lord spoke to Moses, saying,“ Accept these from them, that they may be used in doing the work of the tabernacle of meeting; and you shall give them to the Levites, to every man according to his service.”So Moses took the carts and the oxen, and gave them to the Levites.
