2 Corinthians 11:6-9 New King James Version (NKJV)

6. Even though I am untrained in speech, yet I am not in knowledge. But we have been thoroughly manifested among you in all things.

7. Did I commit sin in humbling myself that you might be exalted, because I preached the gospel of God to you free of charge?

8. I robbed other churches, taking wages from them to minister to you.

9. And when I was present with you, and in need, I was a burden to no one, for what I lacked the brethren who came from Macedonia supplied. And in everything I kept myself from being burdensome to you, and so I will keep myself.
