Mount Hermon is a northern landmark in Deuteronomy’s account of the territory Israel took east of the Jordan. It helps define the scale of the conquests of Sihon and Og, the distribution of the conquered land, and the border of the territory described to the people.

Geographic Names and Extent

In Moses’ retrospective account, Hermon is identified with Mount Sion. The passage also preserves two regional names for the mountain: the Sidonians call it Sirion, while the Amorites call it Senir. These names place the mountain within a landscape understood and spoken of differently by neighboring peoples.

The mountain anchors a broad territorial description extending from Aroer at the edge of the Arnon Valley northward to Hermon. The account includes the Arabah east of the Jordan, Gilead, and Bashan, reaching Salcah and Edrei, cities associated with Og’s kingdom. Hermon thus figures not as an isolated scenic detail but as a marker in the stated reach of the lands taken.

Conquest and Territorial Allotment

The narrative situates the conquest of Og in Bashan after Israel’s defeat of Sihon. Og came out to battle at Edrei; the account attributes Israel’s victory to the LORD, and says that Og, his people, and his land were delivered into Israel’s hand. Israel took all sixty fortified cities of the Argob region, as well as numerous unwalled towns, and the account describes the destruction of the cities and their inhabitants and the taking of livestock and spoil.

The conquered territory was then assigned among the tribes. The Reubenites and Gadites received land from Aroer and part of Gilead; the half-tribe of Manasseh received the rest of Gilead and Bashan, including the kingdom of Og. Moses also recounts that Jair named the Argob region Havvoth-jair, and that Gilead was given to Machir. Hermon consequently belongs to a territorial account that connects military victory with settlement and inheritance.

A Boundary in Moses’ Teaching

Moses recalls the conquests and allotments while preparing Israel to cross the Jordan. The Transjordan tribes are told to cross armed ahead of their fellow Israelites until the others also possess their inheritance; only then may they return to their own holdings. The account makes the land already taken a pledge of the LORD’s aid in the coming campaign, while also distinguishing it from the land still to be entered beyond the Jordan.

Mount Hermon’s place in this description gives geographic form to Moses’ retrospective: the named northern landmark helps measure a territory secured before the crossing, and its surrounding lands become part of the larger promise of inheritance. In Deuteronomy, geography records both what Israel has received and what remains ahead.
