1 Corinthians 9:5, 15

Have we not the right to take along with us a believing wife, as do the rest of the apostles and the Lord’s brothers and Cephas (Peter)?

But I have used none of these privileges, nor am I writing this [to suggest] that any such provision be made for me now. For it would be better for me to die than to have anyone deprive me of my boast [in this matter of financial support].
