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 Israel sent messengers to Sihon king of the Amorites, king of the city of Heshbon, asking, 'Let the people of Israel pass through your land to go to our land.'

20 But Sihon did not trust the Israelites to cross his land. So he gathered all of his people and camped at Jahaz and fought with Israel.

21 "But the Lord, the God of Israel, handed Sihon and his army over to Israel. All the land of the Amorites became the property of Israel.

22 So Israel took all the land of the Amorites from the Arnon River to the Jabbok River, from the desert to the Jordan River.

23 "It was the Lord, the God of Israel, who forced out the Amorites ahead of the people of Israel. So do you think you can make them leave?
