Ezra 7:11-13 ESV
This is a copy of the letter that King Artaxerxes gave to Ezra the priest, the scribe, a man learned in matters of the commandments of the LORD and his statutes for Israel: “Artaxerxes, king of kings, to Ezra the priest, the scribe of the Law of the God of heaven. Peace. And now I make a decree that anyone of the people of Israel or their priests or Levites in my kingdom, who freely offers to go to Jerusalem, may go with you.
