Bede the Venerable — as excerpted in the Catena Aurea on Mark 10:1-12

“(in Marc. 3, 40) Up to this time Mark hath related what our Lord said and did in Galilee; here he begins to relate what He did, taught, or suffered in Judæa, and first indeed across the Jordan on the east; and this is what is said in these words: And he arose from thence, and cometh into the coasts of Jadœa, by the farther side of Jordan; then also on this side Jordan, when He came to Jericho, Bethany, and Jerusalem. And though all the province of the Jews is generally called Judæa, to distinguish it from other nations, more especially, however, its southern portion was called Judæa, to distinguish it from Samaria, Galilee, Decapolis, and the other regions in the same province.”
