'My Flesh' in the Bible

For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.

But I see another law in my body, working against the law of my mind, and making me the servant of the law of sin which is in my flesh.

Thanks [be] to God through Jesus Christ our Lord! So then, I myself with my mind am enslaved to the law of God, but with my flesh [I am enslaved] to the law of sin.

If by any means I may provoke to emulation them which are my flesh, and might save some of them.
