Ezra in Fausset's Bible Dictionary
("the helper," as Nehemiah means "the comforter".)
1. A "ready scribe in the law of Moses" (Ezra 7:6;
Ezra 7:11-12); "a scribe of the words of the commandments of
the Lord and of His statutes to Israel"; "a scribe of the
law of the God of heaven"; "priest"; a worthy descendant of
Hilkiah the priest under Josiah, who "found the book of the
law in the house of the Lord" (2 Chronicles 34:14-15); son
or descendant of Seraiah (not the high priest. Seraiah, Ezra
7:1). See Ezra 7-10; also Nehemiah 8; Nehemiah 12:26.
Resided in Babylon under Artaxerxes Longimanus. His
qualification for his work was "he had prepared his heart to
seek the law of the Lord, and to do it, and to teach in
Israel statutes and judgments." By the king's leave, in the
seventh year of his reign, he took to Jerusalem 1,754
persons, including Israelites, priests, Levites, singers,
porters, and Nethinim (Ezra 7:7; Ezra 8).
The journey occupied four months. They brought free
will offerings, gold, silver, and vessels, from the king and
his counselors, as well as from the Jews abroad. Artaxerxes
empowered him also to draw upon the royal treasurers beyond
the river for further supplies if necessary; also the decree
added. "thou Ezra, after the wisdom of thy God that is in
thine hand, set magistrates and judges which may judge all
the people that are beyond the river, all such as know the
laws of thy God; and teach ye them that know them not." He
committed for safety the charge of the gold and silver to 12
priests and 12 Levites (Ezra 8:24 translated "I separated 12
of the chief priests in addition to Sherebiah, Hashabiah,
and ten of their brethren with them": compare Ezra 8:18-19).
These delivered them up "to the chief of the priests,
Levites. and fathers at Jerusalem, in the chambers of the
house of the Lord."...
