Charles Ellicott Commentary Ezra 2:63

"And the governor said unto them, that they should not eat of the most holy things, till there stood up a priest with Urim and with Thummim." — Ezra 2:63 (ASV)

Tirshatha. —Interchangeable with Pechah, or governor, as Zerubbabel is called in Ezra 5:14 and always in Haggai. It is probably an old Persian term, signifying “The Feared.”

With Urim and with Thummim. —See Exodus 28:30. They were pronounced to be excluded from priestly functions. Without ark or temple, the people had not yet that special presence of Jehovah before which the high priest could “inquire of the Lord by Urim and Thummim.” Zerubbabel might hope that this privilege would return, and thought the official purity of the priestly line of sufficient importance for such an inquiry. But the holy of holies in the new temple never had in it the ancient “tokens”; and by Urim and Thummim Jehovah was never again consulted.
