Charles Ellicott Commentary Ezra 7:11

"Now this is the copy of the letter that the king Artaxerxes gave unto Ezra the priest, the scribe, even the scribe of the words of the commandments of Jehovah, and of his statutes to Israel:" — Ezra 7:11 (ASV)

Even a scribe. —In the case of Ezra, the function of scribe was more important than that of priest. The word scribe originally meant the writer or copier of the law; but now it meant the expositor of its general moral commandments and of its special ceremonial statutes. It is with the latter particularly that the commission of Ezra had to do.
