Korahites
The Korahites in the Bible were that portion of the Kohathites that descended from the Sons of Korah. They were an important branch of the singers of the Kohathite division (2 Chronicles 20:19).
The Sons of Korah were the sons of Moses' cousin Korah. The story of Korah is found in Numbers 16. Korah led a revolt against Moses; he died, along with all his co-conspirators, when God caused "the earth to open her mouth and swallow him and all that appertained to them" (Numbers 16:31-33). However, "the children of Korah died not" (Numbers 26:11). Several psalms are described in their opening verses as being by the Sons of Korah: numbers 42, 44–49, 84, 85, 87 and 88.[1]
Some of the Korahites were also "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).
There is a tradition that the prophet Samuel was descended from Korah.[2]
The psalms-based band Sons of Korah take their name from the Sons of Korah in the Bible.
