“Not boasting of things without our measure, that is, of other men's labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly,”
King James Version (KJV)
10:15 Having hope, now your faith is increased - So that you can the better spare us. To be enlarged by you abundantly - That is, enabled by you to go still further.
2Co 10:15 Not boasting . . . of other men's labours. It was Paul's uniform course to preach where no one before him had preached the gospel. Having hope, etc. The passage expresses the hope that his success at Corinth and the support of the church will enable him to carry the gospel beyond. That city, at this time, was the western limit of his work. The thought is made clear by the next verse.
