Answer: Saul in Tarsus
Explanation: Due to the author´s participation in the book of acts, it can be deduced from the "passages" that Luke was a close collaborator of the Apostle Paul, whose previous name was Saul in Tarsus. For example, the author of acts writes that "when it was decided that we were going to Italy, we delivered Paul and other prisoners to a centurion called July, of the imperial regiment" (Acts 27:1).
