'Fleshly' in the Bible

Brothers, I couldn't speak to you as to spiritual, but as to fleshly, as to babies in Christ.

for you are still fleshly. For insofar as there is jealousy, strife, and factions among you, aren't you fleshly, and don't you walk in the ways of men?

For when one says, "I follow Paul," and another, "I follow Apollos," aren't you fleshly?

If we sowed to you spiritual things, is it a great thing if we reap your fleshly things?
