'Flesh' in the Bible

This, therefore, counselling, did I then use the lightness; or the things that I counsel, according to the flesh do I counsel, that it may be with me Yes, yes, and No, no?

for always are we who are living delivered up to death because of Jesus, that the life also of Jesus may be manifested in our dying flesh,

So that we henceforth have known no one according to the flesh, and even if we have known Christ according to the flesh, yet now we know him no more;

Having, then, these promises, beloved, may we cleanse ourselves from every pollution of flesh and spirit, perfecting sanctification in the fear of God;

for also we, having come to Macedonia, no relaxation hath our flesh had, but on every side we are in tribulation, without are fightings, within -- fears;

and I beseech you, that, being present, I may not have courage, with the confidence with which I reckon to be bold against certain reckoning us as walking according to the flesh;

for walking in the flesh, not according to the flesh do we war,

since many boast according to the flesh, I also will boast:

and that by the exceeding greatness of the revelations I might not be exalted overmuch, there was given to me a thorn in the flesh, a messenger of the Adversary, that he might buffet me, that I might not be exalted overmuch.
