Ezra 7:7

And there went up some of the children of Israel
Perhaps some of the ten tribes, as well as others of the tribes of Judah and Benjamin; who, notwithstanding the edict of Cyrus, chose to remain in Babylon, and in the countries of it, until they saw how things would go in Judea; and hearing that the temple was finished, and that those that had returned had built them houses in their several cities, and prospered, thought fit to return also:

and of the priests, and the Levites, and the singers, and the porters,
and the Nethinims, unto Jerusalem;
to take their places, and execute their offices in the temple now built; for of the Levites especially, some of which were singers, and others porters, and of the Nethinims, there were but few that went up with Zerubbabel: now this journey of theirs was taken

in the seventh year of Artaxerxes the king;
that is, of Darius Artaxerxes, and this was the year after the temple was finished: though it is thought by many learned men, and not without some show of reason, that Artaxerxes Longimanus is meant.
