Numbers 7:3-5

New King James Version

³ 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.

⁴ Then the Lord spoke to Moses, saying, ⁵ “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.”
