The Lord God of Israel hath dispossessed the Amorites - Jephthah shows that the Israelites did not take the land of the Moabites or Ammonites, but that of the Amorites, which they had conquered from Sihon their king, who had, without cause or provocation, attacked them; and although the Amorites had taken the lands in question from the Ammonites, yet the title by which Israel held them was good, because they took them not from the Ammonites, but conquered them from the Amorites. So now the Lord - hath dispossessed the Amorites. - The circumstances in which the Israelites were when they were attacked by the Amorites, plainly proved, that, unless Jehovah had helped them, they must have been overcome. God defeated the Amorites, and made a grant of their lands to the Israelites; and they had, in consequence, possessed them for three hundred years, Judges 11:26.

So now the Lord God of Israel hath dispossessed the Amorites from before his people Israel,.... It is his doing, and not the work of the Israelites; it is he that dispossessed the Amorites, and put the Israelites into the possession of their land, and therefore they enjoy it by a good tenure:

and shouldest thou possess it? what through the blessing of God on their arms they have obtained by conquest, and he has settled them in; did they conquer, that thou should possess what they conquered? did their God put it into their hands to deliver it into thine? did they fight to recover for thee what thou hadst lost, and to put thee into the possession of it? did not they fight in their own defence, and their enemies and their land fell into their hands, and by the laws and right of nations became theirs? and canst thou expect to possess it? what reason is there for it?

From these facts Jephthah drew this simple but indisputable conclusion: "Jehovah the God of Israel has rooted out the Amorites before His people Israel, and thou wilt take possession of it (viz., the land of the Amorites)." The suffix to תּירשׁנּוּ refers to האמרי, the Amorites, i.e., their land. The construction of ירשׁ with the accusative of the people (as in Deuteronomy 2:12, Deuteronomy 2:21-22; Deuteronomy 9:1) may be explained on the simple ground, that in order to take possession of a country, it is necessary first of all to get the holders of it into your power. Jephthah then proved still further how unwarrantable the claim of the king of the Ammonites was, and said to him (Judges 11:24), "Is it not the fact (הלא, nonne), that what thy god Chemosh gives thee for a possession, of that thou takest possession; and all that Jehovah makes ownerless before us, of that we take possession?" - an appeal the validity of which could not be disputed. For Chemosh, see at Numbers 21:29. The verb הורישׁ combines the three meanings: to drive out of a possession, to deprive of a possessor, and to give for a possession; inasmuch as it is impossible to give a land for a possession without driving away or exterminating its former possessor.

So now the LORD God of Israel hath dispossessed the Amorites from before his people Israel, and shouldest thou possess it?

11:23 So the Lord - God, the sovereign Lord of all lands, hath given us this land; this he adds, as a farther and convincing reason; because otherwise it might have been alledged against the former argument, that they could gain no more right to that land from Sihon, than Sihon himself had.

11:12-28 One instance of the honour and respect we owe to God, as our God, is, rightly to employ what he gives us to possess. Receive it from him, use it for him, and part with it when he calls for it. The whole of this message shows that Jephthah was well acquainted with the books of Moses. His argument was clear, and his demand reasonable. Those who possess the most courageous faith, will be the most disposed for peace, and the readiest to make advances to obtain; but rapacity and ambition often cloak their designs under a plea of equity, and render peaceful endeavours of no avail.
