Me (surprised: Kris knows everything there is to know about history, modern or ancient, but, apparently, not this): I looked it up. It means The Ten Cities and refers to these ten cities in what would now be the Jordan area that amounted to the main Greek and Roman cities in that area in the early Common Era. That means the non-Semitic cities.
Kris: What about it?
Me: Well, it says in Matthew’s gospel that, when Jesus started going around healing, people from not only Galilee and
Jerusalem and Judea
followed him but also people from the Decapolis.
That's Greeks and Romans. Right from the beginning. That's, like, people from far away.
(I went and got my Bible and showed him: “Large crowds from Galilee, the Decapolis,
Jerusalem, Judea and the region
followed him” (Matthew 4:25 NIV). Jordan
Kris: Yes, we tend to think Jesus healed people to help them, but actually he did it so that people everywhere would believe.
Me: But he told a lot of the people he healed not to tell anyone, so he couldn’t have healed them to spread the word.
Kris: No, he healed those ones out of compassion.
