1 Corinthians 9:20-22

Mace(i) 20 to the Jews, I became as a Jew, that I might gain the Jews; to those who are under the law, as under the law, that I might gain those who are under the law; 21 to those who are without the law, as without that law, (not as being under no law to God, but as under the law to Christ) that I might gain those who are without the law. 22 to the weak I became as weak, that I might gain the weak: I became all things to all men, that I might save all sorts of men.
