23 And Jesus went about all Galilee, teaching in their synagogues, preaching the gospel of the kingdom, and healing all kinds of sickness and all kinds of disease among the people.
24 Then His fame went throughout all Syria; and they brought to Him all sick people who were afflicted with various diseases and torments, and those who were demon-possessed, epileptics, and paralytics; and He healed them.
25 Great multitudes followed Him—from Galilee, and from Decapolis, Jerusalem, Judea, and beyond the Jordan.
Closely connected with the preaching of the Gospel of the Kingdom was the healing of every disease not spiritual, but every bodily disease and weakness. The healing of disease is always connected with the preaching of the Gospel of the Kingdom. The healings were signs that the King is the Jehovah and that the Kingdom had drawn nigh … It is not the gospel of grace which is preached, but that of the Kingdom. The Gospel of Grace needs no sign outwardly by healing of disease to demonstrate that it is God-given. Nowhere in the Epistles have we the promise that Gospel preaching is to be connected with healing of every bodily weakness and disease. — Gaebelein, page 103.
multitudes (v.25) — [They] came not only from Galilee but from Jerusalem in the south and from the territory of Decapolis and Perea on the east of Jordan. His miracles dealt not simply with trivial diseases but with incurable afflictions, such as epilepsy, palsy, and demon possession. No affliction was beyond His healing touch. The kingdom blessings promised by Isaiah 35:5-6, due for fulfillment in the future kingdom, here became the credentials of the King in His first coming. — Walvoord, page 39
Decapolis (v.25) — a group of ten cities on the eastern frontier of the Roman Empire in Judea and Syria. The ten cities were not an official league or political unit, but they were grouped together because of their language, culture, location, and political status, with each possessing a certain degree of autonomy and self-rule. The Decapolis cities were centers of Greek and Roman culture in a region that was otherwise Jewish. With the exception of Scythopolis, all the cities were east of the Jordan River.
