But thus do unto them,.... As after directed:
that they may live and not die; live long, and not die a sudden and violent death:
when they approach unto the most holy things; the ark, the shewbread table, c. to take them up and carry them:
Aaron and his sons shall go in into the holy and most holy places:
and appoint them in everyone to his service, and to his burden; what everyone shall do, and how they shall take them up, and bear them.
