Charles Ellicott Commentary Ezra 7:12

"Artaxerxes, king of kings, unto Ezra the priest, the scribe of the law of the God of heaven, perfect and so forth." — Ezra 7:12 (ASV)

Artaxerxes, king of kings. —Artachshatra in Persian, Artachshasta in Hebrew. The Persian monarchs inherited the title given here from the Babylonians (Daniel 2:37). It is not used by the historian, only by the king himself.

Perfect peace, and at such a time. —Literally, perfect, and so on. The expression occurs only here, and is a difficult one. Our translation follows the apocryphal Esdras, and is on the whole to be accepted, a salutation being implied.
