Numbers 18:2-4

2And thy brethrenH251 also of the tribeH4294 of LeviH3878, the tribeH7626 of thy fatherH1, bringH7126 thou with thee, that they may be joinedH3867 unto thee, and ministerH8334 unto thee: but thou and thy sonsH1121 with thee shall minister beforeH6440 the tabernacleH168 of witnessH5715.

3And they shall keepH8104 thy chargeH4931, and the chargeH4931 of all the tabernacleH168: only they shall not come nighH7126 the vesselsH3627 of the sanctuaryH6944 and the altarH4196, that neither they, nor ye also, dieH4191.

4And they shall be joinedH3867 unto thee, and keepH8104 the chargeH4931 of the tabernacleH168 of the congregationH4150, for all the serviceH5656 of the tabernacleH168: and a strangerH2114 shall not come nighH7126 unto you.
