Numbers 3:36-39

NSB(i) 36 It was the duty of the Merarites to be in charge of the framework of the inner tent, the crossbars, posts, sockets, and all the equipment. They took care of these things. 37 They were responsible for the posts for the surrounding courtyard, the bases, pegs, and ropes. 38 Moses, Aaron, and his sons put up their tents on the east side in front of the tent of meeting. They were in charge of the holy place on behalf of the Israelites. Anyone else who tried to do the Levites’ duties had to be put to death. 39 The grand total of Levites that Moses and Aaron counted at Jehovah’s command, by families, every male who was at least one month old, was twenty-two thousand.
