'Word of God' in the Bible

And much people shall go and say: come, and let us go up to the hill of the LORD and unto the house of the God of Jacob: that he may teach us his ways, and that we may walk in his paths. For out of Zion shall come the law, and the word of God out of Jerusalem.

Then said Hezekiah to Isaiah, "Good is the word of God which thou hast told me." He said moreover, "For there shall be peace and faithfulness in my time."

Hear the word of God, all ye that fear the thing which he speaketh. Your brethren that hate you, and cast you out for my name's sake, say "Let the LORD magnify himself, that we may see your gladness," and yet they shall be confounded.
