Romans 15:20 in the King James Version
Yea, so have I strived to preach the gospel, not where Christ was named, lest I should build upon another man’s foundation:
Context
19 in the power of signs and wonders, in the power of God’s Spirit; so that from Jerusalem and around as far as to Illyricum, I have fully preached the Good News of Christ;
20 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.
21 But, as it is written, “They will see, to whom no news of him came. They who haven’t heard will understand.”
