2 Corinthians 10:15 in the King James Version
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,
Context
14 For we don’t stretch ourselves too much, as though we didn’t reach to you. For we came even as far as to you with the Good News of Christ,
15 not boasting beyond proper limits in other men’s labors, but having hope that as your faith grows, we will be abundantly enlarged by you in our sphere of influence,
16 so as to preach the Good News even to the parts beyond you, not to boast in what someone else has already done.
