'External' in the Bible
They sent their disciples to him along with the Herodians. They said, "Teacher, we know that you are sincere and that you teach the way of God truthfully. You don't favor any individual, because you pay no attention to external appearance.
They came and told him, "Teacher, we know that you are sincere. You don't favor any individual, because you pay no attention to external appearance. Rather, you teach the way of God truthfully. Is it lawful to pay taxes to Caesar or not? Should we pay them or shouldn't we?"
For a person is not a Jew because of his appearance, nor is circumcision something just external and physical.
These people who want to impress others by their external appearance are trying to force you to be circumcised, simply to avoid being persecuted for the cross of the Messiah.
Why, not even those who are circumcised obey the Law! They simply want you to be circumcised so that they can boast about your external appearance.
Your beauty should not be an external one, consisting of braided hair or the wearing of gold ornaments and dresses.
