For I will not dare to speak of any things except those which Christ worked through me for the obedience of the Gentiles, by word and deed, 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; 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. But, as it is written, “They will see, to whom no news of him came. They who haven’t heard will understand.”

Referring to

Isaiah @isaiah · Isaiah 52:13-15

Behold, my servant will deal wisely. He will be exalted and lifted up, and will be very high. Just as many were astonished at you— his appearance was marred more than any man, and his form more than the sons of men— so he will cleanse many nations. Kings will shut their mouths at him; for they will see that which had not been told them, and they will understand that which they had not heard.
