'Altered' in the Bible

Then Nebuchadnezzar was filled with wrath, and his facial expression was altered toward Shadrach, Meshach and Abed-nego. He answered by giving orders to heat the furnace seven times more than it was usually heated.

Let his mind be altered from that of a human being, and let an animal's mind be given to him, and let seven periods of time go by for him.

Now let the king issue a written interdict so that it cannot be altered, according to the law of the Medes and Persians, which cannot be changed.
