Nehemiah 7:63-65

63 Of the priests: the sons of Hobaiah, the sons of Hakkoz, and the sons of Barzillai, who [was so named because he had] married one of the daughters of Barzillai, the [well-known] Gileadite, and was named after them.

64 These men searched for their ancestral registration among those recorded in the genealogies, but it was not located; so they were excluded from the priesthood as [ceremonially] unclean.

65 The governor told them that they should not eat any of the most holy food until a priest arose with[5] Urim and Thummim [to determine God's will in the matter].
