Ezra 1:3

Who is there among you of all his people? Not of the tribe of Judah only, but of Israel also, who were under his government, the Assyrians and Medes, among whom they were scattered, being his subjects. Accordingly Josephus says, that Zerubbabel sent the edict of Cyrus into Media to the rest of the tribes. His God be with him Let his God help him, as I also shall; and let him go up to Jerusalem Thus he not only makes a proclamation to them of liberty to go to their own country, but desires them to go, and prays God to be with them, and prosper them in building his house, saying, He is the God, and thereby evidently acknowledging him to be the true, if not also the only God.
