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 Seon king of the Amorite, king of Esbon, and Israel said to him, Let us pass, we pray thee, by thy land to our place.

20 And Seon did not trust Israel to pass by his coast; and Seon gathered all his people, and they encamped at Jasa; and he set the battle in array against Israel.

21 And the Lord God of Israel delivered Seon and all his people into the hand of Israel, and they smote him; and Israel inherited all the land of the Amorite who dwelt in that land,

22 from Arnon and to Jaboc, and from the wilderness to Jordan.

23 And now the Lord God of Israel has removed the Amorite from before his people Israel, and shalt thou inherit his ?
