'Testimony of Jesus' in the Bible

who testified to God's word, and of the testimony of Jesus Christ, about everything that he saw.

I John, your brother and partner with you in oppression, Kingdom, and perseverance in Christ Jesus, was on the isle that is called Patmos because of God's Word and the testimony of Jesus Christ.

I fell down before his feet to worship him. He said to me, "Look! Don't do it! I am a fellow bondservant with you and with your brothers who hold the testimony of Jesus. Worship God, for the testimony of Jesus is the Spirit of Prophecy."

I saw thrones, and they sat on them, and judgment was given to them. I saw the souls of those who had been beheaded for the testimony of Jesus, and for the word of God, and such as didn't worship the beast nor his image, and didn't receive the mark on their forehead and on their hand. They lived, and reigned with Christ for a thousand years.
