2 Corinthians 11:7, 9

Or did I [perhaps] sin by humbling myself so that you might be exalted and honored, because I preached God’s gospel to you free of charge?

And when I was with you and ran short [financially], I did not burden any of you; for what I needed was fully supplied by the brothers (Silas and Timothy) who came from Macedonia (the church at Philippi). So I kept myself from being a burden to you in any way, and will continue to do so. [Phil 4:15, 16]
