Numbers 18:1-7 - Provision For The Priesthood
1 And Yahweh said unto Aaron, Thou and thy sons and the house of thy father with thee, shall bear the iniquity of the sanctuary, - and, thou, and thy sons with thee, shall bear the iniquity of your priesthood. 2 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. 3 So shall they keep thy charge, and the charge of all the tent, - only, unto the vessels of the sanctuary, and unto the altar, shall they not come near, lest they die - both they, and ye. 4 So shall they be joined unto thee, and shall keep the charge of the tent of meeting, as to all the laborious work of the tent, - but a stranger, shall not come near unto you.
5 So shall ye keep the charge of the sanctuary, and the charge of the altar, - that there no more be wrath against the sons of Israel. 6 I, therefore, lo! I have taken your brethren the Levites, out of the midst of the sons of Israel, - unto you, as a gift are they given, unto Yahweh, to do the laborious work of the tent of meeting. 7 But thou and thy sons with thee, shall keep the charge of your priesthood, as to every matter of the altar and as to the interior of the veil, and shall do the laborious work, as a laborious service of gifts, do I give your priesthood, and, the stranger who cometh near shall be put to death.
