John Gill Bible Commentary

And the Jebusite,.... Who had their name from Jebus, a third son of Canaan, and from whom Jerusalem was called Jebus, Jdg 19:10 and where his posterity continued to dwell when the land of Canaan was possessed by the Israelites; for they were so strong and powerful, that the men of Judah could not drive them out from thence, and here they remained until the times of David, who dispossessed them of it, Jos 15:63. There is an island near Spain, formerly called Ebusus, now Ibissa, where was one of the colonies of the Phoenicians, in which, Bochart (g) observes, the name of the Jebusites is thought to remain. And the Emorite; so called from Emor, the fourth son of Canaan, commonly called the Amorite, a people so strong and mighty, that they are compared to cedars for height, and to oaks for strength, Amo 2:9 they dwelt both on this and the other side Jordan: Sihon, one of their kings, made war on the king of Moab, and took all his country from him unto Arnon, Num 21:26 and in the times of Joshua there were several kings of the Amorites, which dwelt on the side of Jordan westward, Jos 5:1 hence it may be Amor, in the Arabic tongue signifying to command, and Emir, a commander. And the Girgasite; the same with the Gergesene in Mat 8:28 who, in the times of Christ, lived about Gerasa, or Gadara: a Jewish writer (h) says, that when they left their country to Israel, being forced to it by Joshua, they went into a country which to this day is called Gurgestan.
