'Brothers' in the Bible

So a white robe was given to each of them, and they were told to rest a little while longer until the number would be completed of their fellow slaves and their brothers, who were going to be killed just as they had been.

Then I heard a loud voice in heaven say:The salvation and the powerand the kingdom of our Godand the authority of His Messiahhave now come,because the accuser of our brothershas been thrown out:the one who accuses thembefore our God day and night.

Our brothers conquered him by the blood of the lamb and by the word of their testimony, for they did not cling to their lives even in the face of death.

Then I fell at his feet to worship him, but he said to me, “Don’t do that! I am a fellow slave with you and your brothers who have the testimony about Jesus. Worship God, because the testimony about Jesus is the spirit of prophecy.”

But he said to me, “Don’t do that! I am a fellow slave with you, your brothers the prophets, and those who keep the words of this book. Worship God.”
