Romans 15:19-21

Young's Literal Translation

¹⁹ in power of signs and wonders, in power of the Spirit of God; so that I, from Jerusalem, and in a circle as far as Illyricum, have fully preached the good news of the Christ;

²⁰ and so counting it honour to proclaim good news, not where Christ was named -- that upon another's foundation I might not build --

²¹ but according as it hath been written, `To whom it was not told concerning him, they shall see; and they who have not heard, shall understand.'
