Hesabu 18 : 7 Numbers chapter 18 verse 7

Nawe na wanao pamoja nawe mtautunza ukuhani wenu, kwa ajili ya kila kitu cha madhabahu, na kwa ajili ya vile vilivyomo ndani ya pazia, nanyi mtatumika. Nawapeni ukuhani kuwa utumishi wa kipawa; na mgeni akaribiaye atauawa.

You and your sons with you shall keep your priesthood for everything of the altar, and for that within the veil; and you shall serve: I give you the priesthood as a service of gift: and the stranger who comes near shall be put to death.
