'In Me' in the Bible

My God has sent his [heavenly] agent, and has shut the lions' mouths, and they have not hurt me, inasmuch as before him innocence was found in me. And also before thee, O king, I have done no harm.

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

So I was left alone, and saw this great vision. And there remained no strength in me, for my fitness was turned in me into debility, and I retained no strength.

For how can the servant of this my lord talk with this my lord? For as for me, straightaway there remained no strength in me, nor was there breath left in me.
