'Among' in the Bible

And I went farther in the Jews' religion than a number of my generation among my countrymen, having a more burning interest in the beliefs handed down from my fathers.

And I went up by revelation; and I put before them the good news which I was preaching among the Gentiles, but privately before those who were of good name, so that the work which I was or had been doing might not be without effect.

(Because he who was working in Peter as the Apostle of the circumcision was working no less in me among the Gentiles);

He who gives you the Spirit, and does works of power among you, is it by the works of law, or by the hearing of faith?
