2 Corinthians 11:7-9

Or did I commit a sin in abasing myself that ye might be exalted, because I preached to you the gospel of God for nought? I robbed other churches, taking wages of them that I might minister unto you; and when I was present with you and was in want, I was not a burden on any man; for the brethren, when they came from Macedonia, supplied the measure of my want; and in everything I kept myself from being burdensome unto you, and so will I keep myself.
