Judges 11:21 Meaning and Commentary

Judges 11:21

And the Lord God of Israel delivered Sihon and all his people
into the hand of Israel
So that as Sihon, his people, and his country, fell into the hands of Israel through the victory the Lord gave them over him, they had a divine right to the land now in dispute:

and they smote them:
destroyed him and all his people, as they were ordered to destroy the seven nations of Canaan, of which the Amorites were one, ( Deuteronomy 7:1 ) ,

so Israel possessed all the land of the Amorites, the inhabitants of
that country;
by means of the above victory they came into the lawful and rightful possession of all the land that belonged to the Amorites, who were at that time, and none else, the inhabitants of it; and therefore the Ammonites could have no claim to it, nor was any made till now.

Judges 11:21 In-Context

19 Then the Israelites sent messengers to Sihon, the Amorite king of Heshbon, and asked him for permission to go through his country to their own land.

20 But Sihon would not let Israel do it. He brought his whole army together, camped at Jahaz, and attacked Israel.

21 But the Lord, the God of Israel, gave the Israelites victory over Sihon and his army. So the Israelites took possession of all the territory of the Amorites who lived in that country.

22 They occupied all the Amorite territory from the Arnon in the south to the Jabbok in the north and from the desert on the east to the Jordan on the west.

23 So it was the Lord, the God of Israel, who drove out the Amorites for his people, the Israelites.
