2 Corinthians 10:16
so that we can preach the gospel in the regions beyond you. Then we will not be boasting in the work already done in another man’s territory.
Berean Standard Bible
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.
so as to preach the Good News even to the parts beyond you, not to boast in what someone else has already done.
