Numbers 3:33-39
The Numbering of Merari
3:33 From Merari came the family of the Mahlites and the family of the Mushites; these were the families of Merari.
3:34 Those of them who were numbered, counting every male from a month old and upward, were 6,200.
3:35 Now the leader of the clan of the families of Merari was Zuriel son of Abihail. These were to camp on the north side of the tabernacle.
3:36 The appointed responsibilities of the Merarites included the frames of the tabernacle, its crossbars, its posts, its sockets, its utensils, plus all the service connected with these things,
3:37 and the pillars of the courtyard all around, with their sockets, their pegs, and their ropes.
3:38 But those who were to camp in front of the tabernacle on the east, in front of the tent of meeting, were Moses, Aaron, and his sons. They were responsible for the needs of the sanctuary and for the needs of the Israelites, but the unauthorized person who approached was to be put to death.
3:39 All who were numbered of the Levites, whom Moses and Aaron numbered by the word of the Lord, according to their families, every male from a month old and upward, were 22,000.
