'Fleshly' in the Bible

Dear friends, I urge you as strangers and temporary residents to abstain from fleshly desires that war against you.

For Christ also suffered for sins once for all,the righteous for the unrighteous,that He might bring you to God,after being put to death in the fleshly realmbut made alive in the spiritual realm.

For this reason the gospel was also preached to those who are now dead, so that, although they might be judged by men in the fleshly realm, they might live by God in the spiritual realm.
