To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), to win those under the law.
To the Jews he became like a Jew, and to those under the law like one under the law, so that he might win them.
It shows Paul adapting himself to those shaped by Jewish life.
19Though I am free of obligation to anyone, I make myself a slave to everyone, to win as many as possible. 20To the Jews I became like a Jew, to win the Jews. To those under the law I became like one under the law (though I myself am not under the law), to win those under the law. 21To those without the law I became like one without the law (though I am not outside the law of God but am under the law of Christ), to win those without the law. 22To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. 23I do all this for the sake of the gospel, so that I may share in its blessings.
