'My Flesh' in the Bible

For I am conscious that in me, that is, in my flesh, there is nothing good: I have the mind but not the power to do what is right.

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.

I give praise to God through Jesus Christ our Lord. So with my mind I am a servant to the law of God, but with my flesh to the law of sin.

If in any way those who are of my flesh may be moved to envy, so that some of them may get salvation by me.
