'Priest scribe' in the Bible

Here is a copy of the letter that King Artaxerxes gave to Ezra, the priest-scribe, a scholar in matters concerning the commandments of the LORD and concerning his statutes pertaining to Israel:

Artaxerxes, king of kings, Unto Ezra the priest, scribe of the law of the God of the heavens - To despatch and so forth.

I, Artaxerxes, in my capacity as king, hereby decree to all royal treasuries beyond the Euphrates River that whatever Ezra the priest-scribe of the Law of the God of Heaven, may require of you are to be performed with all due diligence,
