Numbers 18:4-6

Darby Translation

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.

⁶ And I, behold, I have taken your brethren, the Levites, from among the children of Israel; to you are they given as a gift for Jehovah to perform the service of the tent of meeting.
