Then the {l} Spirit of the LORD came upon Jephthah, and he passed over Gilead, and Manasseh, and passed over Mizpeh of Gilead, and from Mizpeh of Gilead he passed over unto the children of Ammon.

(l) That is, the spirit of strength and zeal.

Wesley's Notes

11:29 Spirit came - Indued him with a more than ordinary courage and resolution. Manasseh - That is, Bashan, which the half tribe of Manasseh beyond Jordan inhabited. Mizpeh of Gilead - So called to distinguish it from other cities of the same name, having gathered what forces he suddenly could, he came hither to the borders of the Ammonites.

Margin Jephthah

Jephthah seems to have been judge only of northeast Israel.

Jamieson-Fausset-Brown Bible Commentary

Jud 11:29-31. His Vow.

29, 30. Then the Spirit of the Lord came upon Jephthah-The calm wisdom, sagacious forethought, and indomitable energy which he was enabled to display, were a pledge to himself and a convincing evidence to his countrymen, that he was qualified by higher resources than his own for the momentous duties of his office.

he passed over Gilead, and Manasseh-the provinces most exposed and in danger, for the purpose of levying troops, and exciting by his presence a widespread interest in the national cause. Returning to the camp at Mizpeh, he then began his march against the enemy. There he made his celebrated vow, in accordance with an ancient custom for generals at the outbreak of a war, or on the eve of a battle, to promise the god of their worship a costly oblation, or dedication of some valuable booty, in the event of victory. Vows were in common practice also among the Israelites. They were encouraged by the divine approval as emanating from a spirit of piety and gratitude; and rules were laid down in the law for regulating the performance. But it is difficult to bring Jephthah's vow within the legitimate range (see on [222]Le 27:28).

Matthew Henry's Concise Commentary

11:29-40 Several important lessons are to be learned from Jephthah's vow. 1. There may be remainders of distrust and doubting, even in the hearts of true and great believers. 2. Our vows to God should not be as a purchase of the favour we desire, but to express gratitude to him. 3. We need to be very well-advised in making vows, lest we entangle ourselves. 4. What we have solemnly vowed to God, we must perform, if it be possible and lawful, though it be difficult and grievous to us. 5. It well becomes children, obediently and cheerfully to submit to their parents in the Lord. It is hard to say what Jephthah did in performance of his vow; but it is thought that he did not offer his daughter as a burnt-offering. Such a sacrifice would have been an abomination to the Lord; it is supposed she was obliged to remain unmarried, and apart from her family. Concerning this and some other such passages in the sacred history, about which learned men are divided and in doubt, we need not perplex ourselves; what is necessary to our salvation, thanks be to God, is plain enough. If the reader recollects the promise of Christ concerning the teaching of the Holy Spirit, and places himself under this heavenly Teacher, the Holy Ghost will guide to all truth in every passage, so far as it is needful to be understood.
