1 Corinthians 9:19-23King James Version (KJV)
19 For though I be free from all men, yet have I made myself servant unto all, that I might gain the more.
20 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;
21 To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law.
22 To the weak became I as weak, that I might gain the weak: I am made all things to all men, that I might by all means save some.
23 And this I do for the gospel's sake, that I might be partaker thereof with you.
