'Flesh' in the Bible

Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are set forth for an example, suffering the vengeance of eternal fire.

Likewise also these filthy dreamers defile the flesh, despise dominion, and speak evil of dignities.

And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh.
