'External' in the Bible

But from those who were of high reputation (whatever they were—in terms of individual importance—makes no difference to me; God shows no partiality—He is not impressed with the positions that people hold nor does He recognize distinctions such as fame or power)—well, those who were of reputation contributed nothing to me [that is, they had nothing to add to my gospel message nor did they impose any new requirements on me].

So also we [whether Jews or Gentiles], when we were children (spiritually immature), were kept like slaves under the elementary [man-made religious or philosophical] teachings of the world.

For even the circumcised [Jews] themselves do not [really] keep the Law, but they want to have you circumcised so that they may boast in your flesh [that is, in the fact that they convinced you to be circumcised].
