The 'Amorite' race appeared in the area of the Middle Euphrates, about the time of Abraham (c.1900 B.C. while it should be noted that the city of Tyre was founded in 2,750 B.C.) they had gained control of the whole of Babylonia. Prof. R. B. Dixon, in his Racial History of Man (1923), p. 172, mentions that in the period 2500 B.C. - 1500 B.C. the population of Palestine consisted primarily of 'Mediterranean' and 'Caspian' peoples.
Amorites land was east of the Jordan (Num. 21:13) -- the Arnon is the frontier between Moab and the Amorites. This land of the Amorites reaching "from Arnon to Jabbok, even unto the children of Ammon" (ibid. 24), had been taken away from Moab by Sihon (ibid. 24, 26, 29), who built Heshbon to be his residence (ibid. 26, 27) directly before the immigration of Israel. Amorites dwelling in Jazer are specially mentioned (ibid. 32). These Amorites "which dwelt beyond Jordan" are also referred to (Deut. 1:1, 4, 3:2; I Kings, 4:19; Ps. 135. 136. 19; Josh. 2:10, 9:10).
They seem to have originally occupied the land stretching from the heights west of the Dead Sea ( Gen. 14:7) to Hebron ( 13 (compare 13:8; Deut. 3:8; 4:46-48), embracing "all Gilead and all Bashan" ( Deut. 3:10), with the Jordan valley on the east of the river ( 4:49), the land of the "two kings of the Amorites," Sihon and Og (Deut. 31:4; Josh. 2:10; 9:10).
The five kings of the Amorites were defeated in a great slaughter by Joshua (10:10). They were again defeated at the waters of Merom by Joshua, who smote them till there were none remaining (Josh. 11:8). It is mentioned as a surprising circumstance that in the days of Samuel there was peace between them and the Israelites (1 Sam. 7:14).
The Amorites were fierce warriors who were represented on the Egyptian monuments with fair skins, light hair, blue eyes, curved or hooked noses, and pointed beards. They are supposed to have been men of great stature; their king, Og, is described by Moses as the last "of the remnant of the giants" (Deut. 3:11). Both Sihon and Og were independent kings. Og, king of Bashan, is also called an Amorite in Deut. 3:8, 4. 47, where we learn that Og's territory extended "from the river of Arnon unto Mount Hermon." So the land of the Amorites, which is in Gilead (Judges, 10. 8), seems to have embraced all the territory afterward owned by Israel, east of the Jordan. Deut. 3:9 informs us that the name of Mount Hermon in the language of the Amorites was Shenir.
