'Korahites' in the Bible

And Shallum the son of Kore, the son of Ebiasaph, the son of Korah, and his brethren, of his father's house, the Korahites, were over the work of the service, keepers of the thresholds of the tent: and their fathers had been over the camp of Jehovah, keepers of the entry.

Elkanah, and Isshiah, and Azarel, and Joezer, and Jashobeam, the Korahites,

For the courses of the doorkeepers: of the Korahites, Meshelemiah the son of Kore, of the sons of Asaph.

These were the courses of the doorkeepers; of the sons of the Korahites, and of the sons of Merari.
