Numbers 7:3-5

King James Version

³ And they brought their offering before the Lord, six covered wagons, and twelve oxen; a wagon for two of the princes, and for each one an ox: and they brought them before the tabernacle.

⁴ And the Lord spake unto Moses, saying,

⁵ Take it of them, that they may be to do the service of the tabernacle of the congregation; and thou shalt give them unto the Levites, to every man according to his service.
