However back to my point, Paul went through a RITUAL CLEANSING (mikveh), in keeping with Jewish law, in order to present his alms and offerings to HaShem...
Paul's offerings for the saints in Jerusalem where not from him and were not for YHVH.
Now concerning the collection for the saints, as I have given orders to the churches of Galatia, so you must do also: On the first day of the week let each one of you lay something aside, storing up as he may prosper, that there be no collections when I come. And when I come, whomever you approve by your letters I will send to bear your gift to Jerusalem. But if it is fitting that I go also, they will go with me. (1 Corinthians 16:1-4 NKJV)
But now I am going to Jerusalem to minister to the saints. For it pleased those from Macedonia and Achaia to make a certain contribution for the poor among the saints who are in Jerusalem. 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. Therefore, when I have performed this and have sealed to them this fruit, I shall go by way of you to Spain. (Romans 15:25-28 NKJV)

But my point was that after Paul's conversion he never kept Sukkot.
