Romans 15:28 in the King James Version
When therefore I have performed this, and have sealed to them this fruit, I will come by you into Spain.
Context
27 Yes, it has been their good pleasure, and they are their debtors. For if the Gentiles have been made partakers of their spiritual things, they owe it to them also to serve them in material things.
28 When therefore I have accomplished this, and have sealed to them this fruit, I will go on by way of you to Spain.
29 I know that when I come to you, I will come in the fullness of the blessing of the Good News of Christ.
