Paul of Tarsus - Where did he get his wisdom

[Still_Waters]

We were discussing Paul of Tarsus in yesterday's Bible study class and there was an interesting discussion concerning where Paul got his wisdom relevant to the teachings of Lord Jesus.

Some felt that the insights came during the well-known happening on the road to Damascus after which he grew in knowledge and wisdom by association with the apostles.

Others felt that he met the resurrected Jesus after the Damascus happening and was instructed personally by Jesus.

Still others felt that the Damascus happening inspired Paul to rethink his spiritual reviews and that he went to Arabia (and possibly Mount Sinai as well) to contemplate alone what he had learned.

Perhaps, it's some combination of the above.

In any case, I don't know and I'm curious if anyone here can share what they have discovered on this particular subject.
