'Word of God' in the Bible

Who bare witness to the word of God, and to the testimony of Jesus Christ, as much as he saw.

I John, and your brother, and partaker in pressure, and in the kingdom and patience of Jesus Christ, I was in the island called Patmos, for the sake of the word of God, and for the testimony of Jesus Christ.

And when he opened the fifth seal, I saw under the altar the souls of the slain for the word of God, and for the testimony which they had:

And surrounded with a garment dipped in blood: and his name is called The Word of God.

And I saw thrones, and they sat upon them, and judgment was given them: and the souls of them beheaded with an axe for the testimony of Jesus, and for the word of God, and who worshipped not the wild beast, nor his image, and took not the stamp upon their foreheads, and upon their hands; and they lived and reigned with Christ a thousand years.
