Romans 15:25-29

but now, I say, I go unto Jerusalem, ministering unto the saints. For it hath been the good pleasure of Macedonia and Achaia to make a certain contribution for the poor among the saints that are at Jerusalem. Yea, it hath been their good pleasure; and their debtors they are. For if the Gentiles have been made partakers of their spiritual things, they owe it to them also to minister unto them in carnal things. When therefore I have accomplished this, and have sealed to them this fruit, I will go on by you unto Spain. And I know that, when I come unto you, I shall come in the fulness of the blessing of Christ.
