'Second' in the Bible

And on the second day were gathered together the heads of fathers houses of all the people, the priests, and the Levites, unto Ezra the scribe, even to give attention to the words of the law.

And Joel the son of Zichri was their overseer; and Judah the son of Hassenuah was second over the city.

and Mattaniah the son of Mica, the son of Zabdi, the son of Asaph, who was the chief to begin the thanksgiving in prayer, and Bakbukiah, the second among his brethren; and Abda the son of Shammua, the son of Galal, the son of Jeduthun.
