'Uttered' in the Bible

The king uttered these words: "Is this not the great Babylon that I have built for a royal residence by my own mighty strength and for my majestic honor?"

Also, I wanted to learn the significance of the ten horns on its head and the other horn that had arisen, before which three of them had fallen that is, the horn with eyes and a mouth that uttered magnificent things and which was greater in appearance than its fellows.
