2 Corinthians 10:14-16

14For we stretch not ourselves overmuch, as though we reached not unto you: for we came even as far as unto you in the gospel of Christ:

15not glorying beyond our measure, that is, in other men’s labors; but having hope that, as your faith groweth, we shall be magnified in you according to our province unto further abundance,

16so 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.
