'My Flesh' in the Bible

Is my strength that of stone,or my flesh made of bronze?

My flesh is clothed with maggots and encrusted with dirt.My skin forms scabs and then oozes.

My skin and my flesh cling to my bones;I have escaped by the skin of my teeth.

Why do you persecute me as God does?Will you never get enough of my flesh?

Even after my skin has been destroyed,yet I will see God in my flesh.
