Nehemiah 7:63-65

Living Bible

⁶³ There were also several subclans of priests named after Hobaiah, Hakkoz, and Barzillai (he married one of the daughters of Barzillai the Gileadite and took her family name), ^64-65 whose genealogies had been lost. So they were not allowed to continue as priests or even to receive the priests’ share of food from the sacrifices until the Urim and Thummim had been consulted to find out from God whether or not they actually were descendants of priests.
