'Brethren' in the Bible

Then Jeshua the son of Jozadak and his brothers the priests, and Zerubbabel the son of Shealtiel and his brothers arose, and they built the altar of the God of Israel, to offer burnt offerings on it, as it is written in the Law of Moses, the man of God.

In the second year of their coming to God’s house at Jerusalem, in the second month, Zerubbabel the son of Shealtiel and Jeshua the son of Jozadak began [the work], with the rest of their brothers—the priests and Levites and all who came to Jerusalem from the captivity. They appointed the Levites, from twenty years old and upward, to oversee the work of the house of the Lord.

And whatever seems good to you and to your brothers to do with the rest of the silver and the gold, you may do in accordance with the will of your God.

And I sent them to Iddo, the leading man at the place Casiphia, telling them what to say to Iddo and his brothers, the temple servants at the place Casiphia, that is, to bring us servants (ministers) for the house of our God.

Now among the sons of the priests who had married foreign women were found: of the sons of Jeshua [the high priest] the son of Jozadak, and his brothers—Maaseiah, Eliezer, Jarib, and Gedaliah.
