Judges 11:27

The Lord the Judge be judge this day. — An appeal to the arbitrament of Jehovah to decide on the justice of an appeal to arms. (Comp. Genesis 16:5; Genesis 31:53; Genesis 18:25; 1 Samuel 24:15.)

These verses contain a deeply interesting specimen of what may be called ancient diplomacy, and very powerful and straightforward it is — at once honest, conciliatory, and firm. Jephthah maintains the rights of Israel on three grounds, viz., (1) Right of direct conquest, not from Ammon but from the Amorites (15-20); (2) The decision of God (Judges 11:21), which he supports by an argumentum ad hominem — namely, the acquiescence in this decision of the Moabite god Chemosh (Judges 11:24); (3) Undisputed possession from the first (Judges 11:25). He ends by an appeal to God to approve the justice of his cause.
