2 Corinthians 10:16

so that we may preach the gospel in lands beyond you , without boasting of work already done in another’s area of influence .

so that we can preach the gospel in the regions beyond you. For we do not want to boast about work already done in someone else`s territory.

To preach the gospel in the regions beyond you, and not to boast in another man's line of things made ready to our hand.
