'Word of the Lord' in the Bible

The word of the Lord which came to Micah the Morashtite, in the days of Jotham, Ahaz, and Hezekiah, kings of Judah: his vision about Samaria and Jerusalem.

And a number of nations will go and say, Come, and let us go up to the mountain of the Lord, and to the house of the God of Jacob; and he will give us knowledge of his ways and we will be guided by his word: for from Zion the law will go out, and the word of the Lord from Jerusalem.
