1 Corinthians 9
20 Ref And to the Jews I became as a Jew, that I might gain Jews; to them that are under the law, as under the law, not being myself under the law, that I might gain them that are under the law;
21 Ref to them that are without law, as without law, not being without law to God, but under law to Christ, that I might gain them that are without law.
22 Ref To the weak I became weak, that I might gain the weak: I am become all things to all men, that I may by all means save some.
23 Ref And I do all things for the gospel's sake, that I may be a joint partaker thereof.
