The Philistines were not listed with the native Canaanite tribes. They were sea invaders who settled on Israel's southwest coast around 1200 BC. The Philistines had five cities, each with its own ruler (see 1 Samuel 6:16–17). They are mentioned with the Canaanites because they became Israel's main enemy from Samson's time onward.
The text includes Sidonians and northern Hivites to show that Israel's ideal borders were far north and east of what they actually controlled.
The Hivites were Canaanite (Hamitic) people (Genesis 10:17). Little is known about them. The Gibeonites, who tricked Joshua (Joshua 9:3–27), were Hivites.
Baal-hermon is possibly the largest of the three peaks of Mount Hermon in Israel's northeast corner. Lebo-hamath, in southern Lebanon, marks Israel's northernmost ideal boundary (1 Kings 8:65).
