2 Corinthians 10:16

so as to preach the gospel even unto the parts beyond you, and not to glory in another's province in regard of things ready to our hand. [Though God gave us so vast a bishopric, we indeed filled so much of it as to reach you. We were not so much smaller than this bishopric which God gave to us, that we had to stretch ourselves to cover it. To make a show of covering our territory we did not need to take possession of other men's labors and claim the fruits of their ministry, as though they wrought as our agents. If we had done this, we would indeed be glorying beyond our measure. But thus far (i. e., as far as unto you) we have covered the province assigned to us and we have hope that as your faith groweth, and ye become subject to Christ through being subject to his true ministers, we ourselves shall grow and be magnified so that we shall more nearly attain to the magnitude of our great province. At present your vacillation and infidelity confine our labors to you. Having taken you as a fortress for Christ, we can not leave you assailed by Satan and half surrendered to him. When you are again established in the faith I expect to go on into Italy and into Spain, and do work in those parts of my province which lie far beyond you. It is no part of my plan or intention to take possession of some other man's labor and glory in it, as you false leaders have done by coming to Corinth and taking possession of the church which I left there ready to your hand.]
