Numbers 3:34-38

Their numbered men in the counting of every male from a month old and upward: 6,200.

And the leader of the fathers’ households of the families of Merari was Zuriel the son of Abihail. They were to camp on the northward side of the tabernacle.

Now the appointment of duties of the sons of Merari included the framework of the tabernacle, its bars, its pillars, its bases, all its equipment, and all the service concerning them,

and the pillars around the courtyard with their bases, their pegs, and their ropes.

Now those who were to camp in front of the tabernacle eastward, in front of the tent of meeting toward the sunrise, were Moses and Aaron and his sons, performing the duties of the sanctuary for the obligation of the sons of Israel; but the layman coming near was to be put to death.
