John Gill's Bible Commentary Ver. 9. And afterwards the children of Judah , etc.] After the taking of Bezek, and the king of it, having him to Jerusalem, where he died: they went down ; from Jerusalem; which was on high ground: to fight against the Canaanites that dwelt in the mountain, and in the south, and in the valley ; into which several parts the lot of the tribe of Judah was divided; in each of which they had cities, and some, as it seems, yet unsubdued, and in the hands of the Canaanites; of these several parts, and the cities in them, (see Joshua 15:21,33,48).
Matthew Henry Commentary
Verses 9-20 - The Canaanites had iron chariots; but Israel had God on their side whose chariots are thousands of angels, Ps 68:17. Yet they suffere their fears to prevail against their faith. About Caleb we read in Jo 15:16-19. The Kenites had settled in the land. Israel let them fi where they pleased, being a quiet, contented people. They that moleste none, were molested by none. Blessed are the meek, for they shal inherit the earth.
