Deuteronomy 3:8 Meaning and Commentary

Deuteronomy 3:8

And we took at that time out of the hands of the two kings of
the Amorites
Sihon king of Heshbon, and Og king of Bashan;

the land that [was] on this side Jordan;
where Moses then was, being in the plains of Moab, and was the country beyond Jordan, with respect to the land of Canaan, and when in that:

from the river of Arnon unto Mount Hermon;
Arnon was a river which divided Moab and the Amorites, ( Numbers 22:13 ) and Hermon was a mountain of Gilead, which ended where Lebanon began, and was the northerly border of this country. It was remarkable for the dew that fell on it; (See Gill on Psalms 133:3).

Deuteronomy 3:8 In-Context

6 We completely destroyed the kingdom of Bashan, just as we had destroyed King Sihon of Heshbon. We destroyed all the people in every town we conquered—men, women, and children alike.

7 But we kept all the livestock for ourselves and took plunder from all the towns.

8 “So we took the land of the two Amorite kings east of the Jordan River—all the way from the Arnon Gorge to Mount Hermon.

9 (Mount Hermon is called Sirion by the Sidonians, and the Amorites call it Senir.)

10 We had now conquered all the cities on the plateau and all Gilead and Bashan, as far as the towns of Salecah and Edrei, which were part of Og’s kingdom in Bashan.
