The Amorites are usually found in the mountain Numbers 13:29; Joshua 10:6. Here they dwell in the valley, of which the monuments of Rameses III show them to have been in possession when that monarch invaded Syria. It was their great strength in this district, and their forcible detention of the territory of Dan, which led to the expedition of the Danites Judges 18. The house of Joseph lent their powerful aid in subduing them, probably in the times of the Judges.

The Amorites forced the children of Dan, etc. - Just as the ancient Britons were driven into the mountains of Wales by the Romans; and the native Indians driven back into the woods by the British settlers in America.

And the Amorites forced the children of Dan into the mountain,.... Into the mountainous part of the tribe of Dan; the most noted mountains in it were Sear and Baalah, which lay on the border of Judah, Joshua 15:10; Joppa in this tribe was built on an high rock, and so Gibbethon, as its name seems to import, perhaps was built on a hill or mountain, as were the cities after mentioned:

for they would not suffer them to come down to the valley; which lay between Joppa and Caesarea, the plain of Sharon, in which were Lydda, Jamnia, &c. which belonged to their tribe, and they afterwards enjoyed; See Gill on Joshua 19:48.

Still less were the Danites able to drive the Canaanites out of their inheritance. On the contrary, the Amorites forced Dan up into the mountains, and would not suffer them to come down into the plain. But the territory allotted to the Danytes was almost all in the plain (see at Joshua 19:40). If, therefore, they were forced out of that, they were almost entirely excluded from their inheritance. The Amorites emboldened themselves (see at Deuteronomy 1:5) to dwell in Har-cheres, Ajalon, and Shaalbim. On the last two places see Joshua 19:42, where Ir-shemesh is also mentioned. This combination, and still more the meaning of the names Har-cheres, i.e., sun-mountain, and Ir-shemesh, i.e., sun-town, make the conjecture a very probable one, that Har-cheres is only another name for Ir-shemesh, i.e., the present Ain Shems (see at Joshua 15:10, and Rob. Pal. iii. pp. 17, 18). This pressure on the part of the Amorites induced a portion of the Danites to emigrate, and seek for an inheritance in the north of Palestine (see Judges 18). On the other hand, the Amorites were gradually made tributary by the powerful tribes of Ephraim and Manasseh, who bounded Dan on the north. "The hand of the house of Joseph lay heavy," sc., upon the Amorites in the towns already named on the borders of Ephraim. For the expression itself, comp. 1 Samuel 5:6; Psalm 32:4.

And the Amorites forced the children of Dan into the mountain: for they would not suffer them to come down to the valley:

1:34 The valley - That is, into the plain country; which was the occasion of that expedition for the getting new quarters, of which we read Josh 19:47,48 and chap.Jud 18:1 - 31.

1:21-36 The people of Israel were very careless of their duty and interest. Owing to slothfulness and cowardice, they would not be at the pains to complete their conquests. It was also owing to their covetousness: they were willing to let the Canaanites live among them, that they might make advantage of them. They had not the dread and detestation of idolatry they ought to have had. The same unbelief that kept their fathers forty years out of Canaan, kept them now out of the full possession of it. Distrust of the power and promise of God deprived them of advantages, and brought them into troubles. Thus many a believer who begins well is hindered. His graces languish, his lusts revive, Satan plies him with suitable temptations, the world recovers its hold; he brings guilt into his conscience, anguish into his heart, discredit on his character, and reproach on the gospel. Though he may have sharp rebukes, and be so recovered that he does not perish, yet he will have deeply to lament his folly through his remaining days; and upon his dying bed to mourn over the opportunities of glorifying God and serving the church he has lost. We can have no fellowship with the enemies of God within us or around us, but to our hurt; therefore our only wisdom is to maintain unceasing war against them.
