'Word of God' in the Bible

who bare witness of the word of God, and of the testimony of Jesus Christ, even of all things that he saw.

I John, your brother and partaker with you in tribulation and kingdom and patience which are in Jesus, was in the isle that is called Patmos, for the word of God and the testimony of Jesus.

And when he opened the fifth seal, I saw underneath the altar the souls of them that had been slain for the word of God, and for the testimony which they held:

And he is arrayed in a garment sprinkled with blood: and his name is called The Word of God.

And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that had been beheaded for the testimony of Jesus, and for the word of God, and such as worshipped not the beast, neither his image, and received not the mark upon their forehead and upon their hand; and they lived, and reigned with Christ a thousand years.
