Matthew Poole and continuators on Matthew 4:25

25 And there followed him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judea, and from beyond Jordan.

They followed for the Loaves, for the benefit of the Bodily Cures, or out of Curiosity, tho some (probably) followed him out of Love, and to learn of him, Decapolis hath its name from ten Cities, comprehended in it. Here was a mixture both of Iews and Gentiles following Christ, who came to be a Saviour of them both, and to pull down the Partitionwall betwixt both, to make them both one Gospel-Church, Eph. 2.14.
