New American Standard Bible (NASB)
1 Corinthians 8
11 For through your knowledge he who is weak is ruined, the brother for whose sake Christ died.
12 And so, by sinning against the brethren and wounding their conscience when it is weak, you sin against Christ.
13 Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble.
1 Corinthians 9
1 Am I not free? Am I not an apostle? Have I not seen Jesus our Lord? Are you not my work in the Lord?
2 If to others I am not an apostle, at least I am to you; for you are the seal of my apostleship in the Lord.
3 My defense to those who examine me is this:
4 Do we not have a right to eat and drink?
5 Do we not have a right to take along a believing wife, even as the rest of the apostles and the brothers of the Lord and Cephas?
6 Or do only Barnabas and I not have a right to refrain from working?
7 Who at any time serves as a soldier at his own expense? Who plants a vineyard and does not eat the fruit of it? Or who tends a flock and does not use the milk of the flock?
8 I am not speaking these things according to human judgment, am I? Or does not the Law also say these things?
