Numbers 18:3-5

Darby Translation

³ And they shall keep thy charge, and the charge of the whole tent: only they shall not come near to the vessels of the sanctuary and to the altar, that they may not die, and you as well as they.

⁴ And they shall unite with thee, and keep the charge of the tent of meeting, for all the service of the tent; and no stranger shall come near to you.

⁵ And ye shall keep the charge of the sanctuary, and the charge of the altar; that there come no wrath any more upon the children of Israel.
