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 (2 Chronicles 20:19). Eleven psalms are attributed to the Korahites: Psalm 42, Psalms 44 - 49, Psalm 84, Psalm 85, Psalm 87, and Psalm 88.
Some of the sons of Korah also were "porters" of the temple (1 Chronicles 9:17-19); one of them was over "things that were made in the pans" (v31), i.e., the baking in pans for the meat-offering (Leviticus 2:5).
The psalms based band Sons of Korah take their name from the Korahites in the Bible.
