Romans 15:
20 Yea, so have I strived to preach the gospel, not where Christ was named, lest I should build upon another man’s foundation:
21 But as it is written, To whom he was not spoken of, they shall see: and they that have not heard shall understand.
22 For which cause also I have been much hindered from coming to you.
23 But now having no more place in these parts, and having a great desire these many years to come unto you;
24 Whensoever I take my journey into Spain, I will come to you: for I trust to see you in my journey, and to be brought on my way thitherward by you, if first I be somewhat filled with your company.
Rom.15:20-24
