Numbers 3:33-37

33From Merari came the clans of the Mahlites and Mushites; these were the Merarite clans. 34The number of all the males a month old or more was 6,200.

35The leader of the families of the Merarites was Zuriel son of Abihail; they were to camp on the north side of the tabernacle.

36The duties assigned to the sons of Merari were the tabernacle’s frames, crossbars, posts, bases, and all its equipment—all the service for these items, 37as well as the posts of the surrounding courtyard with their bases, tent pegs, and ropes.
