To what race the Jebusites belonged is doubtful. Their name does not seem Semitic, and they do not make their appearance till after the patriarchal period.
The original name of Jerusalem was Babylonian, Uru-Salim, "the city of Salim," shortened into Salem in Ge 14:18 and in the inscriptions of the Egyptian kings Ramses II and Ramses III. In the Tell el-Amarna Letters (1400 BC) Jerusalem is still known as Uru-Salim, and its king bears a Hittite name, implying that it was at the time in the possession of the Hittites. His enemies, however, were closing around him, and one of the tablets shows that the city was eventually captured and its king slain. These enemies would seem to have been the Jebusites, since it is after this period that the name "Jebus" makes its appearance for the first time in the Old Testament (Jud 19:10,11).
The Jebusite king at the time of the conquest was Adoni-zedek, who met his death at Beth-boron (Jos 10:1 ; in Jos 10:5 the word "Amorite" is used in its Babylonian sense to denote the inhabitants of Canaan generally). The Jebusites were a mountain tribe (Nu 13:29; Jos 11:3). Their capital "Jebus" was taken by the men of Judah and burned with fire (Jud 18), but they regained possession of, and held, the fortress till the time of David (2Sa 5:6 ).
When Jerusalem was taken by David, the lives and property of its Jebusite inhabitants were spared, and they continued to inhabit the temple-hill, David and his followers settling in the new City of David on Mt. Zion (Jos 15:8,63; Jud 1:21; 19:11). And as Araunah is called "king" (2Sa 24:23), we may conclude that their last ruler also had been lowed to live. His name is non-Sem, and the various spellings of it (compare 1Ch 21:15, "Ornan") indicate that the Hebrew writers had some difficulty in pronouncing it. The Jebusites seem ultimately to have blended with the Israelite population.
