Usually it is assumed, that Paul was not married. It is true, that a wife of him is never mentioned in the bible, but still there is some evidence:
Acts 26,10:
And that is just what I did in
Jerusalem. On the authority of the chief priests I put many of the
saints in prison, and when they were put to death, I cast my vote
against them.
This indicates, that Paul was a member of the Sanhedrin, the great council. How else could he possibly vote for somebodys death?
To be member of the Sanhedrin, a man had to be married!
