Romans 15:25-27 New King James Version (NKJV)
25 But now I am going to Jerusalem to minister to the saints. 26 For it pleased those from Macedonia and Achaia to make a certain contribution for the poor among the saints who are in Jerusalem. 27 It pleased them indeed, and they are their debtors. For if the Gentiles have been partakers of their spiritual things, their duty is also to minister to them in material things.
