'Brothers' in the Bible

And to each one of them a white robe was given, and it was said to them that they should rest yet a short time, until [the number of] their fellow slaves and their brothers who were about to be killed as they [had been] were completed also.

And I heard a loud voice in heaven saying, "Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, because the accuser of our brothers has been thrown down, the one who accuses them before our God day and night.

And I fell down before his feet to worship him, and he said to me, "{Do not do that!} I am a fellow slave of you and of your brothers who hold to the testimony of Jesus. Worship God! For the testimony of Jesus is the spirit of prophecy."

And he said to me, "{Do not do that!} I am your fellow slave, and of your brothers the prophets, and of those who keep the words of this book. Worship God!"
