2 “But bring with you also your brothers, the tribe of Levi, the tribe of your father, that they may be ajoined with you and serve you, while you and your sons with you are before the tent of the testimony.

3 “And they shall thus attend to your obligation and the obligation of all the tent, but athey shall not come near to the furnishings of the sanctuary and bthe altar, or both they and you will die.

4 “They shall be joined with you and attend to the obligations of the tent of meeting, for all the service of the tent; but an 1outsider may not come near you.

5 “So you shall attend to the aobligations of the sanctuary and the obligations of the altar, bso that there will no longer be wrath on the sons of Israel.

6 “Behold, I Myself ahave taken your 1fellow Levites from among the sons of Israel; they are ba gift to you, 2dedicated to the Lord, to perform the service for the tent of meeting.

7 “But you and your sons with you shall aattend to your priesthood for everything concerning the altar and inside the veil, and you are to perform service. I am giving you the priesthood as ba 1bestowed service, but cthe 2outsider who comes near shall be put to death.”
