Ezra 2:61-63

And of the sons of the priests: sons of Habaiah, sons of Koz, sons of Barzillai (who took from the daughters of Barzillai the Gileadite a wife, and is called by their name;)

these have sought their register among those reckoning themselves by genealogy, and they have not been found, and they are redeemed from the priesthood,

and the Tirshatha saith to them, that they eat not of the most holy things till the standing up of a priest with Urim and with Thummim.
