'Physical' in the Bible

For he is not a [real] Jew who is only one outwardly, nor is [true] circumcision something external and physical.

When we were living in the flesh [trapped by sin], the sinful passions, which were awakened by [that which] the Law [identifies as sin], were at work in our body to bear fruit for death [since the willingness to sin led to death and separation from God].

For just as in one [physical] body we have many parts, and these parts do not all have the same function or special use,

But clothe yourselves with the Lord Jesus Christ, and make no provision for [nor even think about gratifying] the flesh in regard to its improper desires.
