The site of this new Luz is not known, but "the land of the Hittites" was apparently in the north of Palestine, on the borders of Syria (Genesis 10:15 note).

The land of the Hittites - Probably some place beyond the land of Canaan, in Arabia, whither this people emigrated when expelled by Joshua. The man himself appears to have been a Hittite, and to perpetuate the name of his city he called the new one which he now founded Luz, this being the ancient name of Beth-el.

And the man went into the land of the Hittites,.... With his family; Kimchi says this was not one of the seven nations of Canaan; and it is very clear from this narrative, that the land this man went to was not in the land of Canaan; though it is certain a people of this name formerly dwelt there, Genesis 15:20; and the land of Canaan is called the land of the Hittites, Joshua 1:4; these either might flee to another country upon Joshua's entry into the land of Canaan, or a colony of them from thence might settle elsewhere, to which this man chose to go, who might be originally of them:

and built a city; his family was numerous, and he a man of wealth, and was allowed to carry all his substance with him:

and called the name of it Luz; in memory of the place he left, and had long lived in. There is a city called Loussa, among the cities which Josephus says (s) were taken by the Jews from the Arabians; and which is very probably the Lysa of Ptolemy (t), which he places in Arabia Petraea, and might be the same with this Luz; and, if so, this shows the land this man went into was in Edom, which is not unlikely; there is another Luza, which Jerom (u) says fell to the lot of the sons of Joseph, near Sichem, three miles from Neapolis:

which is the name thereof unto this day: the time of the writing of this book; See Gill on Judges 1:21.

The man whom they had permitted to go free, went with his family into the land of the Hittites, and there built a town, to which he gave the name of his earlier abode, viz., Luz. The situation of this Luz is altogether unknown. Even the situation of the land of the Hittites cannot be more precisely determined; for we find Hittites at Hebron in the times of Abraham and Moses (Genesis 23), and also upon the mountains of Palestine (Numbers 13:29), and at a later period on the north-east of Canaan on the borders of Syria (1 Kings 10:29). That the Hittites were one of the most numerous and widespread of the tribes of the Canaanites, is evident from the fact that, in Joshua 1:4, the Canaanites generally are described as Hittites.

And the man went into the land of the Hittites, and built a city, and called the name thereof Luz: which is the name thereof unto this day.

1:26 The Hittites - Where the Hittites seated themselves after they were driven out of Canaan, which seems to be northward from Canaan, and near upon it.

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.
