Numbers 3:33-39

33Of Merari was the family of the Mahlites, and the family of the Mushites: these are the families of Merari. 34And those that were numbered of them, according to the number of all the males, from a month old and upward, were six thousand and two hundred. 35And the head of the house of the father of the families of Merari was Zuriel the son of Abihail: these shall encamp on the side of the tabernacle northward. 36And under the custody and charge of the sons of Merari shall be the boards of the tabernacle, and its bars, and its pillars, and its sockets, and all its vessels, and all the service concerning it,1 37And the pillars around the court, and their sockets, and their pins, and their cords. 38But those that encamp before the tabernacle toward the east, even before the tabernacle of the congregation eastward, shall be Moses, and Aaron and his sons, keeping the charge of the sanctuary for the charge of the children of Israel; and the stranger that cometh near shall be put to death. 39All that were numbered of the Levites, whom Moses and Aaron numbered at the commandment of the LORD, throughout their families, all the males from a month old and upward, were twenty and two thousand.
