And after the ascension of Jesus, Jude was one of the first apostles to leave Jerusalem for a foreign country. Jude is believed to have evangelized the area of Armenia, in company perhaps of the apostle Bartholomew, and for a brief time, with the apostle Thomas.
Jude also spent his years of evangelization in Syria and northern Persia (modern Iran).
It is likely that he was martyred there and buried in Kara Kalisa near the Caspian Sea, about 40 miles from Tabriz, in modern day Iran. It is understood he was killed with a sword.
