'Second' in the Bible

On the second day were gathered together the heads of fathers' [houses] of all the people, the priests, and the Levites, to Ezra the scribe, even to give attention to the words of the law.

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 brothers; and Abda the son of Shammua, the son of Galal, the son of Jeduthun.
