Numbers 3:35 (KJV)

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

And 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.

And the chief of the house of the father of the families of Merari was Zuriel the son of Abihail: these shall pitch on the side of the tabernacle northward.

And under the custody and charge of the sons of Merari shall be the boards of the tabernacle, and the bars thereof, and the pillars thereof, and the sockets thereof, and all the vessels thereof, and all that serveth thereto,

And the pillars of the court round about, and their sockets, and their pins, and their cords.
