Discovery Box1 Corinthians 9:16-23 
Context9:16 For if I preach the gospel, I have no reason for boasting, because I am compelled to do this. Woe to me if I do not preach the gospel! 9:17 For if I do this voluntarily, I have a reward. But if I do it unwillingly, I am entrusted with a responsibility. 9:18 What then is my reward? That when I preach the gospel I may offer the gospel free of charge, and so not make full use of my rights in the gospel.
9:19 For since I am free from all I can make myself a slave to all, in order to gain even more people. 1 9:20 To the Jews I became like a Jew to gain the Jews. To those under the law I became like one under the law (though I myself am not under the law) 2 to gain those under the law. 9:21 To those free from the law I became like one free from the law (though I am not free from God’s law but under the law of Christ) to gain those free from the law. 9:22 To the weak I became weak in order to gain the weak. I have become all things to all people, so that by all means I may save some.
9:23 I do all these things because of the gospel, so that I can be a participant in it.
1 tn Or “more converts.” The word “people” is not in the Greek text, but is implied. It has been supplied in the translation to clarify the meaning.
2 tc The Byzantine text, as well as a few other witnesses (D2 [L] Ψ 1881 Ï) lack this parenthetical material, while geographically widespread, early, and diverse witnesses have the words (so א A B C D* F G P 33 104 365 1175 1505 1739 al latt). The phrase may have dropped out accidentally through homoioteleuton (note that both the preceding phrase and the parenthesis end in ὑπὸ νόμον [Jupo nomon, “under the law”]), or intentionally by overscrupulous scribes who felt that the statement “I myself am not under the law” could have led to license.
