Numbers 3:33-39 English Standard Version (ESV)
33 To Merari belonged the clan of the Mahlites and the clan of the Mushites: these are the clans of Merari. 34 Their listing according to the number of all the males from a month old and upward was 6,200. 35 And the chief of the fathers' house of the clans of Merari was Zuriel the son of Abihail. They were to camp on the north side of the tabernacle. 36 And the appointed guard duty of the sons of Merari involved the frames of the tabernacle, the bars, the pillars, the bases, and all their accessories; all the service connected with these; 37 also the pillars around the court, with their bases and pegs and cords.
38 Those who were to camp before the tabernacle on the east, before the tent of meeting toward the sunrise, were Moses and Aaron and his sons, guarding the sanctuary itself, to protect[a] the people of Israel. And any outsider who came near was to be put to death. 39 All those listed among the Levites, whom Moses and Aaron listed at the commandment of the Lord, by clans, all the males from a month old and upward, were 22,000.

33 To Merari belonged the clans of the Mahlites and the Mushites; these were the Merarite clans. 34 The number of all the males a month old or more who were counted was 6,200. 35 The leader of the families of the Merarite clans was Zuriel son of Abihail; they were to camp on the north side of the tabernacle. 36 The Merarites were appointed to take care of the frames of the tabernacle, its crossbars, posts, bases, all its equipment, and everything related to their use, 37 as well as the posts of the surrounding courtyard with their bases, tent pegs and ropes.
38 Moses and Aaron and his sons were to camp to the east of the tabernacle, toward the sunrise, in front of the tent of meeting. They were responsible for the care of the sanctuary on behalf of the Israelites. Anyone else who approached the sanctuary was to be put to death.
39 The total number of Levites counted at the Lord’s command by Moses and Aaron according to their clans, including every male a month old or more, was 22,000.
