a country to the north-west of Macedonia, on the eastern shores of the Adriatic, now almost wholly comprehended in Dalmatia, a name formerly given to the southern part of Illyricum ( 2 Timothy 4:10 ). It was traversed by Paul in his third missionary journey ( Romans 15:19 ). It was the farthest district he had reached in preaching the gospel of Christ. This reference to Illyricum is in harmony with Acts 20:2 , inasmuch as the apostle's journey over the parts of Macedonia would bring him to the borders of Illyricum.
