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 And Israel sent messengers to Sihon king of the Amorites, who ruled in Heshbon, and said to him, ‘Please let us pass through your land into our own place.’

20 But Sihon would not trust Israel to pass through his territory. So he gathered all his people, encamped in Jahaz, and fought with Israel.

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

22 seizing all the land from the Arnon to the Jabbok and from the wilderness to the Jordan.

23 Now since the LORD, the God of Israel, has driven out the Amorites from before His people Israel, should you now possess it?
