Concise Bible Dictionary:
The descendants of Canaan the son of Ham, of whom the Jebusites, the Amorites, the Girgashites, the Hivites, the Arkites, the Sinites, the Arvadites, the Zemarites, and the Hamathites were branches. They were “spread abroad, and the border of the Canaanites was from Sidon, as thou comest to Gerar, unto Gaza: as thou goest unto Sodom and Gomorrha, and Admah, and Zeboim, even unto Lasha” (Gen. 10:15-19). In Genesis 15:18-21, where the land promised to Abram extends to the river Euphrates, there are ten nations mentioned: the Kenites, the Kenizzites, the Kadmonites, the Hittites, the Perizzites, the Rephaims, the Amorites, the Canaanites, the Girgashites, and the Jebusites (Deut. 7:1; Josh. 3:10). Here and elsewhere the Canaanites are only one people of many; whereas in other places the term Canaanite appears to include any of the inhabitants of Canaan, as in Joshua 17:12-13; Nehemiah 9:24; Obadiah 20 and Zechariah 14:21. The same Hebrew word is translated “merchant” (Job 41:6; Prov. 31:24; Isa. 23:8); so the passage in Zechariah 14:21 may signify “there shall no more be the merchant in the house of the Lord of hosts” (compare John 2:16).
