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 And we utterly destroyed them, as we had done to King Sihon of Heshbon, in each city utterly destroying men, women, and children.

7 But all the livestock and the plunder of the towns we kept as spoil for ourselves.

8 So at that time we took from the two kings of the Amorites the land beyond the Jordan, from the Wadi Arnon to Mount Hermon

9 (the Sidonians call Hermon Sirion, while the Amorites call it Senir),

10 all the towns of the tableland, the whole of Gilead, and all of Bashan, as far as Salecah and Edrei, towns of Og's kingdom in Bashan.
