'Of the Flesh' in the Bible

But I have some things against you, because you have with you those who keep the teaching of Balaam, by whose suggestion Balak made the children of Israel go out of the right way, taking food which was offered to false gods, and going after the desires of the flesh.

But I have this against you, that you let the woman Jezebel say she is a prophet and give false teaching, making my servants go after the desires of the flesh and take food offered to false gods.

And they had no regret for putting men to death, or for their use of secret arts, or for the evil desires of the flesh, or for taking the property of others.

But those who are full of fear and without faith, the unclean and takers of life, those who do the sins of the flesh, and those who make use of evil powers or who give worship to images, and all those who are false, will have their part in the sea of ever-burning fire which is the second death.
