Numbers 3:33

Of Merari was the family of the Mahlites, and the family of the Mushites: these are the families of Merari.

The Merarites stood as one of the three divisions of the Levites, with each division assigned its own distinct duties in the care of the tabernacle. From Merari came two families, the Mahlites and the Mushites. Their camping place was on the north side of the tabernacle. Their charge was its pillars, sockets, boards, and related parts.
