Judges 11:24

Wilt not thou possess that which Chemosh thy god giveth thee - As if he had said: "It is a maxim with you, as it is among all nations, that the lands which they conceive to be given them by their gods, they have an absolute right to, and should not relinquish them to any kind of claimant. You suppose that the land which you possess was given you by your god Chemosh and therefore you will not relinquish what you believe you hold by a Divine right. Now, we know that Jehovah, our God, who is the Lord of heaven and earth, has given the Israelites the land of the Amorites; and therefore we will not give it up." The ground of Jephthah's remonstrance was sound and good.

1. The Ammonites had lost their lands in their contests with the Amorites.

The Israelites conquered these lands from the Amorites, who had waged a most unprincipled war against them.

God, who is the Maker of heaven and earth had given those very lands as a Divine grant to the Israelites.

In consequence of this they had possession of them for upwards of three hundred years.

5. These lands were never reclaimed by the Ammonites, though they had repeated opportunities of doing it, whilst the Israelites dwelt in Heshbon, in Aroer, and in the coasts of Arnon; but they did not reclaim them because they knew that the Israelites held them legally. The present pretensions of Ammon were unsupported and unjustifiable.
