2 Corinthians 10:15-16

New King James Version

¹⁵ not boasting of things beyond measure, that is, ^(A)in other men’s labors, but having hope, that as your faith is increased, we shall be greatly enlarged by you in our sphere, ¹⁶ to preach the gospel in the regions beyond you, and not to boast in another man’s sphere of accomplishment.
