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!"
