Ezra 2:59-63 - Those Of Unknown Origin
59 And these were they who went up from Tel-melah, Tel-harhsa, Cherub, Addan, and Immer: but they could not prove their father's house, and their descent, whether they were of Israel:
60 The children of Delaiah, the children of Tobiah, the children of Nekoda, six hundred fifty and two. 61 And of the children of the priests: the children of Habaiah, the children of Hakkoz, the children of Barzillai; who took a wife of the daughters of Barzillai the Gileadite, and was called after their name: 62 These sought their listing among those that were reckoned by genealogy, but they were not found: therefore were they, as defiled, excluded from the priesthood. 63 And the governor said unto them, that they should not eat of the most holy things, till a priest could consult with Urim and with Thummim.
