'In Me' in the Bible

My God has sent His Angel, and has shut the lions' mouths, and they have not hurt me, because before Him purity was found in me. And also before you, O king, I have done no harm.

Therefore I was left alone, and saw this great vision, and there remained no strength in me. For my beauty was turned within me to corruption, and I kept no strength.

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