1 Chronicles 9:19

And Shallum, the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, of the house of his father, the Korahites, were over the work of the service, keepers of the gates of the Tabernacle, as briefly stated above; and their fathers, being over the host of the Lord, were keepers of the entry; the descendants of Korah, as a branch of the Kohathites, had been in charge of the entrance of the Tabernacle in the wilderness at the time of Moses, as their descendants, in turn, were in charge of the Temple gates.
