“And unto the Jews I became as a Jew, that I might gain the Jews; to them that are under the law, as under the law, that I might gain them that are under the law;”
King James Version (KJV)
9:20 To the Jews I became as a Jew - Conforming myself in all things to their manner of thinking and living, so far as; I could with innocence. To them that are under the law - Who apprehend themselves to be still bound by the Mosaic law. As under the law - Observing it myself, while I am among them. Not that he declared this to be necessary, or refused to converse with those who did not observe it. This was the very thing which he condemned in St. Peter, #Gal 2:14|.
1Co 9:20 Unto the Jews I became as a Jew. With Jews he lived as a Jew in order to reach them. He observed their distinctions of meats, kept feasts (Ac 18:21), and circumcised Timothy (Ac 16:3). He observed the law to reach those who kept law.
