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 Israel then sent messengers to Sihon king of the Amorites, king of Heshbon, and Israel said to him, 'Please let us pass through your land to our country,'

20 but Sihon did not trust Israel to pass through his territory, so Sihon gathered all his people together and encamped at Jahaz and fought with Israel.

21 And the LORD, the God of Israel, gave Sihon and all his people into the hand of Israel, and they defeated them. So Israel took possession of all the land of the Amorites, who inhabited that country.

22 And they took possession of all the territory of the Amorites from the Arnon to the Jabbok and from the wilderness to the Jordan.

23 So then the LORD, the God of Israel, dispossessed the Amorites from before his people Israel; and are you to take possession of them?
