Ezra 2:61-63

61And of the children of the priests: the children of Habaiah, the children of Koz, the children of Barzillai; who took a wife of the daughters of Barzillai the Gileadite, and was called after their name.

62These sought their genealogical register, but they were not found; therefore were they, as polluted, removed from the priesthood.

63And the Tirshatha said to them that they should not eat of the most holy things, till there stood up a priest with Urim and with Thummim.
