'Testimony of Jesus' in the Bible

He bore witness of the Word of God, and of the testimony of Jesus Christ, even of all the things that he saw.

I, John, who am your brother and who share with you in the woes and kingdom and stedfastness of Jesus, found myself in the island called Patmos, for the sake of the word of God and the testimony of Jesus.

And the dragon was enraged at the woman, and went away to make war upon the rest of her children who keep the commandments of God, and hold fast the testimony of Jesus. And he stood upon the sand of the sea.

And I fell down at his feet to worship him, and he said to me. "See that you do it not. I am a fellow slave of yours and of your brothers who hold the testimony of Jesus; for the testimony of Jesus is the vital breath of prophecy."

And I saw thrones, and those who sat on them, and they were permitted to judge; and I saw the souls of those who had been beheaded for the testimony of Jesus, and for the Word of God, those who did not worship the beast nor his image, and who did not receive his brand upon their brow, or hands. And they lived and reigned with Christ for a thousand years.
