Ezra 2:61-63

The Voice

⁶¹ Three priestly lines—the descendants of Habaiah, Hakkoz, and Barzillai (so called because he married a daughter of Barzillai the Gileadite)— ⁶² could not be located in their genealogies. Therefore they were considered ritually impure and excluded from the priesthood in case they should taint the Lord’s new temple. ⁶³ The governor decided they should abstain from eating the most holy things until the high priest could divine answers using the Urim and Thummim.
