'My Flesh' in the Bible

Then a spirit passed before my face; the hair of my flesh stood up:

Is my strength the strength of stones? or is my flesh of brass?

My flesh is clothed with worms and clods of dust; my skin is broken and become lothsome.

Why do I take my flesh in my teeth, and put my life in my hand?

My bone cleaveth to my skin and to my flesh, and I have escaped with the skin of my teeth.

Why do ye persecute me as God, and are not satisfied with my flesh?

And though after my skin worms destroy this body, yet in my flesh shall I see God:

Even when I remember I am afraid, and trembling taketh hold on my flesh.
