Bamidbar 4:27 Meaning and Commentary

Numbers 4:27

At the appointment of Aaron and his sons
As they shall order and direct:

shall be all the service of the sons of the Gershonites;
everyone of them was to take their share, as Aaron and his sons should appoint them:

in all their burdens, and in all their service;
what each of them should carry, and in what they should perform duty:

and ye shall appoint to them in charge all their burdens;
charge them carefully to keep all that were committed to them to bear, that none be lost, not a pin nor a cord.
