Parallel
Numbers 18:4
Brenton's English Septuagint · Berean Standard Bible
And they shall be joined to thee, and shall keep the charges of the tabernacle of witness, in all the services of the tabernacle; and a stranger shall not approach to thee.
They are to join you and attend to the duties of the Tent of Meeting, doing all the work at the Tent; but no outsider may come near you.
