Numbers 18:2-6

JPS_ASV_Byz(i) 2 And thy brethren also, the tribe of Levi, the tribe of thy father, bring thou near with thee, that they may be joined unto thee, and minister unto thee, thou and thy sons with thee being before the tent of the testimony. 3 And they shall keep thy charge, and the charge of all the Tent; only they shall not come nigh unto the holy furniture and unto the altar, that they die not, neither they, nor ye. 4 And they shall be joined unto thee, and keep the charge of the tent of meeting, whatsoever the service of the Tent may be; but a common man shall not draw nigh unto you. 5 And ye shall keep the charge of the holy things, and the charge of the altar, that there be wrath no more upon the children of Israel. 6 And I, behold, I have taken your brethren the Levites from among the children of Israel; for you they are given as a gift unto the LORD, to do the service of the tent of meeting.
