And thy brethren also of the tribe of Levi, the tribe of thy father, bring thou with thee, that they may be joined to thee, and minister to thee: but thou and thy sons with thee shall minister before the tabernacle of witness.
Therefore thou and thy sons with thee shall keep your priest's office for every thing of the altar, and within the vail; and ye shall serve: I have given your priest's office to you as a service of gift: and the stranger that cometh nigh shall be put to death.
And the LORD spoke to Aaron, Behold, I also have given thee the charge of my heave-offerings of all the hallowed things of the children of Israel; to thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever.
This shall be thine of the most holy things reserved from the fire: every oblation of theirs, every meat-offering of theirs, and every sin-offering of theirs, and every trespass-offering of theirs, which they shall render to me, shall be most holy for thee and for thy sons.
And this is thine; the heave-offering of their gift, with all the wave-offerings of the children of Israel: I have given them to thee, and to thy sons, and to thy daughters with thee, by a statute for ever: every one that is clean in thy house shall eat of it.
Every thing that openeth the matrix in all flesh, which they bring to the LORD, whether of men or beast, shall be thine: nevertheless, the first born of man shalt thou surely redeem, and the firstling of unclean beasts shalt thou redeem.
But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat for an offering made by fire, for a sweet savor to the LORD.
All the heave-offerings of the holy things, which the children of Israel offer to the LORD, have I given to thee, and to thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the LORD to thee and to thy seed with thee.
But the Levites shall do the service of the tabernacle of the congregation, and they shall bear their iniquity: It shall be a statute for ever throughout your generations, that among the children of Israel they have no inheritance.
But the tithes of the children of Israel, which they offer as a heave-offering to the LORD, I have given to the Levites to inherit: therefore I have said to them, Among the children of Israel they shall have no inheritance.
Thus speak to the Levites, and say to them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up a heave-offering of it for the LORD, even a tenth part of the tithe.
