'Thoughts' in the Bible

as for you, O king, your thoughts came [into your mind] on your bed, what should happen hereafter; and he who reveals secrets has made known to you what shall happen.

But as for me, this secret is not revealed to me for any wisdom that I have more than any living, but to the intent that the interpretation may be made known to the king, and that you may know the thoughts of your heart.

I saw a dream which made me afraid; and the thoughts on my bed and the visions of my head troubled me.

Then Daniel, whose name was Belteshazzar, was stricken mute for a while, and his thoughts troubled him. The king answered, Belteshazzar, don't let the dream, or the interpretation, trouble you. Belteshazzar answered, My lord, the dream be to those who hate you, and its interpretation to your adversaries.

Then the king's face was changed in him, and his thoughts troubled him; and the joints of his thighs were loosened, and his knees struck one against another.

[Now] the queen by reason of the words of the king and his lords came into the banquet house: the queen spoke and said, O king, live forever; don't let your thoughts trouble you, nor let your face be changed.

Here is the end of the matter. As for me, Daniel, my thoughts much troubled me, and my face was changed in me: but I kept the matter in my heart.
