'Fleshly' in the Bible

In him you also were circumcised -- not, however, with a circumcision performed by human hands, but by the removal of the fleshly body, that is, through the circumcision done by Christ.

Let no one who delights in humility and the worship of angels pass judgment on you. That person goes on at great lengths about what he has supposedly seen, but he is puffed up with empty notions by his fleshly mind.

Even though they have the appearance of wisdom with their self-imposed worship and false humility achieved by an unsparing treatment of the body -- a wisdom with no true value -- they in reality result in fleshly indulgence.
