'Exhausted' in the Bible

I, Daniel, was exhausted and sick for days. Then I got up and again carried out the king's business. But I was astonished at the vision, and there was no one to explain it.

Then I heard the man clothed in linen who was over the waters of the river as he raised both his right and left hands to the sky and made an oath by the one who lives forever: "It is for a time, times, and half a time. Then, when the power of the one who shatters the holy people has been exhausted, all these things will be finished."
