1 Corinthians 9:20
To the Jews I became like a Jew in order to win Jews. To those under the Law I became like a man under the Law, in order to win those under the Law (although I myself am not under the Law).
It is enough for a disciple to be like his teacher and a slave to be like his master. If they have called the head of the house Beelzebul, how much more will they do the same to those of his household!"
A disciple is not better than his teacher. But everyone who is fully-trained will be like his teacher.
But we'll agree to your request, only if you will become like us by circumcising every male among you.

In answer, all of them will tell you, "You've also become as weak as we are! You have become just like us!'
Paul replied, "Whether quickly or not, I wish to God that not only you but everyone listening to me today would become what I am except for these chains!"
I beg you, brothers, to become like me, since I became like you. You did not do anything wrong to me.
When the crowds saw what Paul had done, they shouted in the Lycaonian language, "The gods have become like men and have come down to us!"
