'Word of God' in the Bible

when Annas and Caiaphas were high-priests, the word of God came to John the son of Zacharias in the wilderness;

And Jesus answered him, saying, It is written, "Man shall not live by bread alone, but by every word of God."

AND it came to pass, as the multitude were thronging upon him, in order to hear the word of God, that he was standing by the lake of Gennesaret:

Now this is the parable: The seed is the word of God.

Then he answered and said to them, My mother and my brethren are they, who hear the word of God, and practise it.

But he said, Yea rather, blessed are they who hear the word of God and observe it.
