2 Corinthians 11:7-10, 12

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] As the truth of Christ is in me, my boast [of independence] will not be silenced in the regions of Achaia (southern Greece).

But what I am doing I will keep doing, [for I am determined to keep this independence] in order to cut off the claim of those who want an opportunity to be regarded just as we are in the things they brag about.
