What was paul occupation as he traveled as a missionary?

Paul was a Pharisee before he became a Christian.

(Acts 23:6) 6 Now when Paul took note that the one part was of Sadducees but the other of Pharisees, he proceeded to cry out in the San′he·drin: "Men, brothers, I am a Pharisee, a son of Pharisees. Over the hope of resurrection of the dead I am being judged."

(Acts 18:1-3) After these things he departed from Athens and came to Corinth. 2 And he found a certain Jew named Aq′ui·la, a native of Pon′tus who had recently come from Italy, and Pris·cil′la his wife, because of the fact that Claudius had ordered all the Jews to depart from Rome. So he went to them 3 and on account of being of the same trade he stayed at their home, and they worked, for they were tentmakers by trade.
