Numbers Chapter 4 Verse 28This [is] the service of the families of the sons of Gershon in the tabernacle of the congregation: and their charge [shall be] under the hand of Ithamar the son of Aaron the priest.

Cut ye not off the tribe of the families of the Kohathites from among the Levites:

But thus do unto them, that they may live, and not die, when they approach unto the most holy things: Aaron and his sons shall go in, and appoint them every one to his service and to his burden:

But they shall not go in to see when the holy things are covered, lest they die.

And the LORD spake unto Moses, saying,

Take also the sum of the sons of Gershon, throughout the houses of their fathers, by their families;

From thirty years old and upward until fifty years old shalt thou number them; all that enter in to perform the service, to do the work in the tabernacle of the congregation.

This [is] the service of the families of the Gershonites, to serve, and for burdens:

And they shall bear the curtains of the tabernacle, and the tabernacle of the congregation, his covering, and the covering of the badgers' skins that [is] above upon it, and the hanging for the door of the tabernacle of the congregation,

And the hangings of the court, and the hanging for the door of the gate of the court, which [is] by the tabernacle and by the altar round about, and their cords, and all the instruments of their service, and all that is made for them: so shall they serve.

At the appointment of Aaron and his sons shall be all the service of the sons of the Gershonites, in all their burdens, and in all their service: and ye shall appoint unto them in charge all their burdens.

As for the sons of Merari, thou shalt number them after their families, by the house of their fathers;

From thirty years old and upward even unto fifty years old shalt thou number them, every one that entereth into the service, to do the work of the tabernacle of the congregation.

And this [is] the charge of their burden, according to all their service in the tabernacle of the congregation; the boards of the tabernacle, and the bars thereof, and the pillars thereof, and sockets thereof,

And the pillars of the court round about, and their sockets, and their pins, and their cords, with all their instruments, and with all their service: and by name ye shall reckon the instruments of the charge of their burden.

This [is] the service of the families of the sons of Merari, according to all their service, in the tabernacle of the congregation, under the hand of Ithamar the son of Aaron the priest.

And Moses and Aaron and the chief of the congregation numbered the sons of the Kohathites after their families, and after the house of their fathers,

From thirty years old and upward even unto fifty years old, every one that entereth into the service, for the work in the tabernacle of the congregation:

And those that were numbered of them by their families were two thousand seven hundred and fifty.

These [were] they that were numbered of the families of the Kohathites, all that might do service in the tabernacle of the congregation, which Moses and Aaron did number according to the commandment of the LORD by the hand of Moses.

And those that were numbered of the sons of Gershon, throughout their families, and by the house of their fathers,
