The Hittites were from Anatolia, which is now north-central Turkey. They set up colonies in distant places like Syria and were also linked to Canaan in the list of ancient nations (see Genesis 10:15; 23:3–20). The Hittite empire ended suddenly around 1200 BC. But people called Hittites still lived in Israel, such as "Uriah the Hittite" (2 Samuel 11:3; 23:39).
It is impossible to prove that the Hittites of Anatolia were the same as those mentioned in the Old Testament, but they were probably similar in some ways.
Girgashites were an otherwise unknown Canaanite group (Genesis 10:16–17).
For Amorites, see study note on Deuteronomy 1:4.
The Canaanites were the original people of Canaan, living there since 3000 BC. They descended from Noah’s son Ham (see Genesis 9:18–27).
The Perizzites are not in the Table of Nations (Genesis 10:16–17), so they might not have any connection to the Canaanites.
Many scholars think the Hivites were the same as the Horites (or Hurrians; see study note on Deuteronomy 2:1). They were a non-Semitic group found throughout the ancient Near East.
The Jebusites had a connection to Jerusalem (Judges 1:21; 2 Samuel 5:6–8). King David bought land from Araunah the Jebusite to build an altar (2 Samuel 24:15–25). This site was where Solomon later built his temple (2 Chronicles 3:1).
