'Desires of the Flesh' in the Bible

In my letter I said to you that you were not to keep company with those who go after the desires of the flesh;

But the sense of my letter was that if a brother had the name of being one who went after the desires of the flesh, or had the desire for other people's property, or was in the way of using violent language, or being the worse for drink, or took by force what was not his, you might not keep company with such a one, or take food with him.

Have you not knowledge that evil-doers will have no part in the kingdom of God? Have no false ideas about this: no one who goes after the desires of the flesh, or gives worship to images, or is untrue when married, or is less than a man, or makes a wrong use of men,

Food is for the stomach and the stomach for food, and God will put an end to them together. But the body is not for the desires of the flesh, but for the Lord; and the Lord for the body:

Keep away from the desires of the flesh. Every sin which a man does is outside of the body; but he who goes after the desires of the flesh does evil to his body.

But because of the desires of the flesh, let every man have his wife, and every woman her husband.

Again, let us not give way to the desires of the flesh, as some of them did, of whom twenty-three thousand came to their end in one day.
