'Word of God' in the Bible

I JOHN, who am your brother, and partake in the tribulation, in the reign, and in the patience of Jesus Christ, was in the isle called Patmos, for the word of God, and for the testimony I gave of Jesus Christ.

When he had opened the fifth seal, I saw under the altar the souls of those that were slain for the word of God, and for the testimony which they maintain'd.

I saw likewise thrones, where persons were seated, to whom the power of judging was given: and I saw the souls of those that were beheaded for the testimony they had given to Jesus, and for the word of God, who had not worshipped the beast, nor his image, nor had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
