'Brothers' in the Bible

He had brothers, the sons of Jehoshaphat: Azariah, Jehiel, Zechariah, Azaryahu, Michael, and Shephatiah. All of these were the sons of Jehoshaphat king of Israel.

but have walked in the way of the kings of Israel, and caused Judah and the inhabitants of Jerusalem to be unfaithful [to God] as the house of Ahab was unfaithful, and you have also murdered your brothers, your father’s house (your own family), who were better than you,

It came about that when Jehu was executing judgment on the house of Ahab, he found the leaders of Judah and the sons of Ahaziah’s [murdered] brothers ministering to Ahaziah, and he killed them.

Conaniah also, and Shemaiah and Nethanel, his brothers, and Hashabiah and Jeiel and Jozabad, officers of the Levites, contributed to the Levites for the Passover offerings 5,000 from the flocks [of lambs and young goats], and 500 bulls.
