Numbers 18:2-4

2And thy brethren alsoH1571, the tribeH4294 of LeviH3878, the tribeH4294 of thy fatherH1, bringH7126 thou near with thee, that they may be joined unto thee, and minister unto thee: but thou and thy sonsH1121 with thee shall be before the tentH168 of the testimonyH5715.

3And they shall keepH8104 thy chargeH4931, and the chargeH4931 of all the TentH168: onlyH389 they shall not come nigh unto the vesselsH3627 of the sanctuaryH6944 and unto the altarH4196, that they dieH4191 not, neither they, nor ye.

4And they shall be joined unto thee, and keepH8104 the chargeH4931 of the tentH168 of meetingH4150, for all the serviceH5656 of the TentH168: and a stranger shall not come nigh unto you.
