Joshua 12:2
Sihon king of the Amorites, who lived in Heshbon. He ruled from Aroer on the rim of the Arnon Valley, along the middle of the valley, up to the Jabbok River (the border of the Ammonites), that is, half of Gilead,
Sihon king of the Amorites,

Sihon controlled a formidable Amorite kingdom east of the Jordan. When he refused Israel passage through his land and attacked them, the Lord delivered his army to Israel at Jahaz (Numbers 21:21–31; Deuteronomy 2:26–35). His defeat opened the Transjordan for Israel’s settlement and displayed God’s faithfulness to give His people the land He had promised.

Num 21:21 Then Israel sent messengers to Sihon king of the Amorites,…
Deu 2:24 Arise, set out, and cross the Arnon Valley.…

who lived in Heshbon.

Heshbon was Sihon’s royal capital, situated on the high plateau east of the Jordan River. Sihon had previously taken it from Moab, making it the center of his expanded dominion (Numbers 21:26). Israel’s capture of Heshbon ended Amorite control of the region and later provided a city within Reuben’s inheritance.

Num 21:25 Israel captured all the cities of the Amorites…
Deu 2:26 So from the Wilderness of Kedemoth I sent messengers…
Num 21:26 Heshbon was the city of Sihon king of the Amorites…

He ruled from Aroer on the rim of the Arnon Valley,

Aroer stood near the Arnon River, which formed the southern boundary of the territory Israel took from Sihon. The victory extended to the full borderland formerly held by the Amorites, leaving no remaining stronghold from which Sihon’s kingdom could be restored.

Deu 2:36 Aroer on the rim of the Arnon Valley, along with the city…
Deu 3:8 At that time we took from the two kings of the Amorites…

along the middle of the valley,

Israel gained control not only of the cities on the plateau but also of the strategic valley routes. Possession of this region secured movement through the land and demonstrated the completeness of the Lord’s victory over Sihon.

Jos 13:9 The area from Aroer on the rim of the Arnon Valley,…
Num 21:14 Therefore it is stated in the Book of the Wars of the LORD:…

up to the Jabbok River (the border of the Ammonites),

The Jabbok marked the northern limit of Sihon’s kingdom and the boundary beyond which Israel did not advance against Ammon, in obedience to God’s command (Deuteronomy 2:19). The same river recalls Jacob’s encounter with God, where he was renamed Israel (Genesis 32:22–32), linking Israel’s inheritance to God’s covenant purposes.

Deu 3:16 and to the Reubenites and Gadites I gave the territory…
Num 21:24 And Israel put him to the sword and took possession…
Deu 2:37 But you did not go near the land of the Ammonites…

that is, half of Gilead,

Gilead was a fertile upland region valued for its pastureland and strategic position. The land taken from Sihon became the inheritance of Reuben, Gad, and the half-tribe of Manasseh (Numbers 32:33–40). Israel’s possession of half of Gilead showed that the promised inheritance had begun before the nation crossed the Jordan.

Num 32:33 So Moses gave to the Gadites, to the Reubenites…
Deu 3:12 So at that time we took possession of this land…

Gilgal, in Deuteronomy 11:30 what the Place Was.
That which is said by Moses, that "Gerizim and Ebal were over-against Gilgal," Deuteronomy 11:30, is so obscure, that it is rendered into contrary significations by interpreters. Some take it in that sense, as if it were near to Gilgal: some far off from Gilgal: the Targumists read, "before Gilgal": while, as I think, they do not touch the difficulty; which lies not so much in the signification of the word Mul, as in the ambiguity of the word Gilgal. These do all seem to understand that Gilgal which

The Lake of Gennesaret; Or, the Sea of Galilee and Tiberias.
Jordan is measured at one hundred and twenty furlongs, from the lake of Samochonitis to that of Gennesaret. That lake, in the Old Testament, is 'The sea of Chinnereth,' Numbers 34:11, &c. In the Targumists, 'The sea of Genesar'; sometimes, 'of Genesor'; sometimes, 'of Ginosar': it is the same also in the Talmudists, but most frequently 'The sea of Tiberiah.' Both names are used by the evangelists; 'the lake of Gennesaret,' Luke 5:1; 'the sea of Tiberias,' John 21:1; and 'the sea of Galilee,' John

Joshua
The book of Joshua is the natural complement of the Pentateuch. Moses is dead, but the people are on the verge of the promised land, and the story of early Israel would be incomplete, did it not record the conquest of that land and her establishment upon it. The divine purpose moves restlessly on, until it is accomplished; so "after the death of Moses, Jehovah spake to Joshua," i. 1. The book falls naturally into three divisions: (a) the conquest of Canaan (i.-xii.), (b) the settlement of the
