1 Corinthians 9:12 If others share the right over you, do we not more? Nevertheless, we did not use this right, but we endure all things so that we will cause no hindrance to the gospel of Christ.

1 Corinthians 9:18 What then is my reward? That, when I preach the gospel, I may offer the gospel without charge, so as not to make full use of my right in the gospel.

2 Corinthians 11:7 Or did I commit a sin in humbling myself so that you might be exalted, because I preached the gospel of God to you without charge?

2 Corinthians 11:9 and when I was present with you and was in need, I was not a burden to anyone; for when the brethren came from Macedonia they fully supplied my need, and in everything I kept myself from being a burden to you, and will continue to do so.

2 Corinthians 12:14 Here for this third time I am ready to come to you, and I will not be a burden to you; for I do not seek what is yours, but you; for children are not responsible to save up for their parents, but parents for their children. (NASB ©1995)
