But Nadab and Abihu died before Yahweh when they brought near strange fire before Yahweh in the desert of Sinai, and sons, had they none,—so then Eleazar and Ithamar ministered as priests, in the presence of Aaron their father.
Therefore also thy brethren of the tribe of Levi the stem of thy father, bring thou near with thee, and let them be joined unto thee, and let them wait upon thee,—both on thee and on thy sons with thee, before the tent of the testimony.
Nor to the priests the Levites, shall there be wanting—A man, before me, To offer an ascending-sacrifice, or To make a perfume with a gift, or To offer a peace- offering, all the days!
Yet shall they remain in my sanctuary As attendants in charge at the gates of the house,— And attending upon the house,— They shall slay the ascending-offering, and the sacrifice of the people, And they, shall stand before them to wait upon them.
and Aaron shall offer the Levites as a wave-offering before Yahweh, from among the sons of Israel,—so shall they be for performing the laborious work of Yahweh.
