'Fleshly' in the Bible

yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach—

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 man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,

Although these have a reputation of wisdom by promoting ascetic practices, humility, and severe treatment of the body, they are not of any value in curbing self-indulgence.
