1 Corinthians 9:12

Fourth, the precedent of the practice of other Christian leaders supported Paul’s point. As the planter of the Corinthian church Paul had a right to the support of the Corinthians more than any of their other ministers did. Yet he did not insist on his right. He chose rather to support himself so his work of establishing the church might not suffer from criticism that he was serving for the material benefits he derived from his converts.
