Numbers 7:4 ASV

²  that the princes of Israel, the heads of their fathers' houses, offered. These were the princes of the tribes, these are they that were over them that were numbered:

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

⁴  And Jehovah spake unto Moses, saying,

⁵  Take it of them, that they may be 'used' in doing the service of the tent of meeting; and thou shalt give them unto the Levites, to every man according to his service.

⁶  And Moses took the wagons and the oxen, and gave them unto the Levites.
