Mishnah Yoma
The high priest performs the service in eight pieces of clothing, and the common priest in four: in tunic, breeches, a headdress, and a sash. The high priest adds the breastpiece, the ephod, the robe and the frontlet. In these were the Urim and Tummim inquired of. But they were not inquired of except by the king, by the head of the court or by one whom the community needs.
