1Co 1 Corinthians, chapter First Epistle to the Corinthians, chapter 9
To those who don't operate according to the law,9:21. Meaning those who are not Jews, who do not observe the law of Moses. I behave like them (though not disregarding God's law, but operating under the law of Christ), so that I might gain those who don't observe the law.1Co 7:18
