1CO 9:15

15 However, I have not requested that you [give me] those things that I have a right [to receive from you]. Furthermore, I am writing this to you, not in order to request you to begin [giving me financial help now]. I would rather die than to [receive help from you]. I do not want anyone to prevent me from boasting [about my proclaiming God’s message to you without receiving financial help from you].
