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 Yisra'el sent messengers to Sichon king of the Amori, the king of Heshbon; and Yisra'el said to him, Let us pass, we pray you, through your land to my place.

20 But Sichon didn't trust Yisra'el to pass through his border; but Sichon gathered all his people together, and encamped in Yahatz, and fought against Yisra'el.

21 The LORD, the God of Yisra'el, delivered Sichon and all his people into the hand of Yisra'el, and they struck them: so Yisra'el possessed all the land of the Amori, the inhabitants of that country.

22 They possessed all the border of the Amori, from the Arnon even to the Yabbok, and from the wilderness even to the Yarden.

23 So now the LORD, the God of Yisra'el, has dispossessed the Amori from before his people Yisra'el, and should you possess them?
