2 Corinthians 11:5-9

Yet I consider myself in no way inferior to the [so-called] super-apostles. But even if I am unskilled in speaking, yet I am not [untrained] in knowledge [I know what I am talking about]; but we have made this evident to you in every way, in all things. 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? I robbed other churches by accepting [more than their share of] financial support for my ministry to you. 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]
