1 Chronicles 9:19

And Shallum, the son of Kore, the son of Ebiasaph, the son of Korah, and his brothers, of his family, the Korahites, were responsible for everything which had to be done in connection with the order of worship, keepers of the doors of the Tent; their fathers had had the care of the tents of the Lord, being keepers of the doorway.
