<p>13:23- see on 1 Thess. 2:17.</p><p><em>Be informed that our brother Timothy has been set at liberty; along with whom, if he comes soon, I will see you- </em>This is a strong indication that Paul was the author, writing from Italy (:24), where it seems Timothy was also imprisoned. Paul expressed his concern for the situation in Jerusalem by sending Timothy to them. His begging of Timothy to come to him in 2 Tim. 4 was therefore asking a fair favour of Timothy, seeing timid Timothy had apparently been imprisoned with Paul at some stage. Although it has to be said that there is no specific implication that the place of Timothy's imprisonment was Rome.</p>
