Here we find the HolySpirit speaking to Paul through others about his soulish desire to go to Jerusalem.

Apparently even the great Apostle Paul was guilty of shutting the HolySpirit down when He advised him counter to his own wishes.
So, the HolySpirit spoke through others to warn Paul.

We know that all things work together for good to them that love the Lord Rom 8:28.

What was good about Paul going to Jerusalem, being taken prisoner, being sent up the line to judges, ending up under house arrest in Rome?
Paul had time to write the letters that we find in the NewTestament.
