9 But ^etake care that this right of yours does not somehow become a ^fstumbling block to the weak.

15 But ^cI have made no use of any of these rights, nor am I writing these things to secure any such provision. For I would rather die than have anyone deprive me of my ^dground for boasting.

18 What then is my reward? That in my preaching I may present the gospel ^hfree of charge, so as not to make full use of my right in the gospel.
