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:

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.
