11:24 Wilt not thou - He speaks according to their absurd opinion: the Ammonites and Moabites got their land by conquest of the old inhabitants, whom they cast out; and this success, though given them by the true God, for Lot's sake, Deut 2:9,19, they impiously ascribe to their god Chemosh, whose gift they owned to be a sufficient title.

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.
