Bible Meaning: Ten cities, the ten city region
Strong's Concordance #G1179
The Decapolis was a group of ten, possibly more, cities within a region that was primary located east of the Jordan River and southeast of the Sea of Galilee. It is only recorded by name three times in the New Testament. It did not become a part of a Roman province until the reign of Emperor Trajan (98 to 117 A.D.).
Biblical references to places within the Decapolis region include "the country of the Gadarenes" (Mark 5:1) and "the country of the Gergesenes" (Matthew 8:28). It is one of the few areas Jesus visited where Gentiles (non-Jews) composed the majority of the population.
The Bible does not name which ten or so cities are considered the Decapolis. Pliny's Natural History (published c. 77 A.D.), however, lists the cities as Gerasa, Scythopolis, Hippos, Gadara, Pella, Philadelphia, Capitolias (Dion), Canatha, Raphana and Damascus.
Matthew 4:23, 25
And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people . . .
And there followed him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judaea, and from beyond Jordan.
And he departed, and began to publish in Decapolis how great things Jesus had done for him: and all men did marvel.
