Korahites
The Korahites in the Bible were that portion of the Kohathites that descended from Korah.
They were an important branch of the singers of the Kohathite division . Eleven psalms are attributed to the Korahites: Psalm 42, Psalms 44 - 49, Psalm 84, Psalm 85, Psalm 87, and Psalm 88.1
Some of the sons of Korah also were "porters" of the temple ; one of them was over "things that were made in the pans" (v31), i.e., the baking in pans for the meat-offering .
The psalms based band Sons of Korah take their name from the Korahites in the Bible.
