'Spirit' in the Bible

In the second year of the reign of Nebuchadnezzar, Nebuchadnezzar dreamed dreams; and his spirit was troubled, and his sleep went from him.

The king said to them, I have dreamed a dream, and my spirit is troubled to know the dream.

But at the last Daniel came in before me, whose name was Belteshazzar, according to the name of my god, and in whom is the spirit of the holy gods: and I told the dream before him, [saying],

Belteshazzar, master of the magicians, because I know that the spirit of the holy gods is in you, and no secret troubles you, tell me the visions of my dream that I have seen, and its interpretation.

This dream I, king Nebuchadnezzar, have seen; and you, Belteshazzar, declare the interpretation, because all the wise men of my kingdom are not able to make known to me the interpretation; but you are able; for the spirit of the holy gods is in you.

There is a man in your kingdom, in whom is the spirit of the holy gods; and in the days of your father light and understanding and wisdom, like the wisdom of the gods, were found in him; and the king Nebuchadnezzar your father, the king, [I say], your father, made him master of the magicians, enchanters, Chaldeans, and soothsayers;

because an excellent spirit, and knowledge, and understanding, interpreting of dreams, and showing of dark sentences, and dissolving of doubts, were found in the same Daniel, whom the king named Belteshazzar. Now let Daniel be called, and he will show the interpretation.

I have heard of you, that the spirit of the gods is in you, and that light and understanding and excellent wisdom are found in you.

But when his heart was lifted up, and his spirit was hardened so that he dealt proudly, he was deposed from his kingly throne, and they took his glory from him:

Then this Daniel was distinguished above the presidents and the satraps, because an excellent spirit was in him; and the king thought to set him over the whole realm.

As for me, Daniel, my spirit was grieved in the midst of my body, and the visions of my head troubled me.
