Titus 3:12
When I send Artemas or Tychicus to you, do your best to come to me at Nicopolis, for I have decided to spend the winter there — the personal note authenticates the epistle, shifting to practical logistics. Nicopolis (city of victory) in Epirus was the imperial city of Augustus; Paul plans winter quarters there. The delegation of Artemas or Tychicus relieves Titus, allowing his journey to Paul. The note anchors the letter in historical circumstance.
