Dalmatia
Dalmatia is named once, in a brief census of where Paul's coworkers had scattered during his final imprisonment. Of the three destinations listed, two are defections of a sort and one is a continuing assignment; Dalmatia falls in the third category.
Titus's Assignment
The verse pairs Titus's name with the place: "for Demas forsook me, having loved this present age, and went to Thessalonica; Crescens to Galatia, Titus to Dalmatia" (2Ti 4:10). The grammar groups all three names in a single sentence, but the relations differ. Demas is described as forsaking Paul, his motive named ("having loved this present age"); Crescens and Titus simply have destinations. Dalmatia stands at the eastern end of the line — a province on the far side of the Adriatic, the most distant of the three points — and Titus's posting there is given without commentary on his motive. The place serves as the limit of the network: the news of Paul's circle has traveled from Rome out as far as Dalmatia, with Titus as the named worker on that end of the field.
