Numbers 18:4-6

21st Century King James Version

⁴ And they shall be joined unto thee, and keep the charge of the tabernacle of the congregation for all the service of the tabernacle; and a stranger shall not come nigh unto you.

⁵ And ye shall keep the charge of the sanctuary and the charge of the altar, that there be 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 they are given as a gift for the Lord, to do the service of the tabernacle of the congregation.
