Ezra 2:62-63 ▼

62 These searched [for their names] among those registered in the genealogies, but they were not found; so they were excluded from the priesthood as [ceremonially] unclean.

63 The governor told them that they should not eat of the most holy things [the priests’ food] until a priest stood up with Urim and Thummim [who by consulting these articles in his breastplate could determine God’s will in the matter].
