'Brothers' in the Bible

And Abner was very angry at the words of Ish-bosheth, and he said, Am I a dog's head of Judah? I am this day doing all in my power for the cause of your father Saul and for his brothers and his friends, and have not given you up into the hands of David, and now you say I have done wrong with a woman.

You are my brothers, my bone and my flesh; why are you the last to get the king back again?
