Romans 15:20
In this way I have aspired to preach the gospel where Christ was not known, so that I would not be building on someone else’s foundation.
Berean Standard Bible
Yea, so have I strived to preach the gospel, not where Christ was named, lest I should build upon another man’s foundation:
yes, making it my aim to preach the Good News, not where Christ was already named, that I might not build on another’s foundation.
