Jephthah uttered all his words before the Lord in Mizpeh - This phrase designates the presence of the tabernacle, or the ark, or of the high priest with Urim and Thummim Judges 20:26; Judges 21:2; Joshua 18:8; 1 Samuel 21:7. The high priest waited upon Jephthah with the ephod, and possibly the ark, at his own house (see Judges 20:18 here). A trace of Jephthah's claim to unite all Israel under his dominion is found in Judges 12:2, and breathes through his whole message to the king of the Ammonites. See Judges 11:12, Judges 11:15, Judges 11:23, Judges 11:27.

Jepthah went with the elders - The elders had chosen him for their head; but, to be valid, this choice must be confirmed by the people; therefore, it is said, the people made him head. But even this did not complete the business; God must be brought in as a party to this transaction; and therefore Jephthah uttered all his words before the Lord - the terms made with the elders and the people on which he had accepted the command of the army; and, being sure of the Divine approbation, he entered on the work with confidence.

Then Jephthah went with the elders of Israel,.... From the land of Tob into the land of Gilead, his native country:

and the people made him head and captain over them; ratified and confirmed what the elders had promised, and by a general unanimous vote appointed him both to be the captain of their forces, and to be the chief ruler and governor of them. And this they did, though he was the son of an harlot; and according to the law in Deuteronomy 23:2, such an one was not to be a civil magistrate; but this was a case of necessity, and in which, no doubt, they were directed by the Lord, who could dispense with his own law: besides, they had come to such an agreement before they had pitched on any particular person, that who should begin to fight with the children of Ammon should be head over all the inhabitants of Gilead so that they were obliged to it by their vote and decree, when they assembled at Mizpeh, where it is probable they consulted the Lord, and acted under his direction, Judges 10:17 and where this was confirmed, as seems from the following clause:

and Jephthah uttered all his words before the Lord in Mizpeh; where the congregation of Israel were assembled, and in which the Shechinah, or divine Majesty, dwelt, as is observed by Jarchi and Kimchi, and not Mizpeh in Joshua 11:3, as the latter says, but this was on the other side Jordan, in the land of Gilead; however, as it was a solemn meeting, the Lord was there, and, as in his presence, Jephthah rehearsed all that passed between him and the elders of Gilead; and, no doubt, in prayer to God, desired he would signify his approbation and ratification of their agreement, and would give him success in his undertakings against the children of Ammon.

Then Jephthah went with the elders of Gilead, "and the people (i.e., the inhabitants of Gilead) made him head and captain, and Jephthah spoke all his words before Jehovah at Mizpeh:" i.e., he repeated in a solemn assembly of the people, before God at Mizpeh, the conditions and obligations under which he would accept the honour conferred upon him. "Before Jehovah" does not necessarily presuppose the presence of the ark at Mizpeh; nor can we possibly assume this, since the war was resolved upon primarily by the eastern tribes alone, and they had no ark at all. It merely affirms that Jephthah performed this act, looking up to God, the omnipresent head of Israel. Still less do the words warrant the assumption that there was an altar in Mizpeh, and that sacrifices were offered to confirm the treaty, of which there is not the slightest indication in the text. "'Before Jehovah' implies nothing more than that Jephthah confirmed all his words by an oath" (Hengstenberg, Diss. ii. pp. 35, 36).

Then Jephthah went with the elders of Gilead, and the people made him head and captain over them: and Jephthah uttered all his words before the LORD in Mizpeh.

11:11 All his words - Or, all his matters, the whole business. Before the Lord - That is, before the public congregation, wherewith God was usually, and then especially present.

11:1-11 Men ought not to be blamed for their parentage, so long as they by their personal merits roll away any reproach. God had forgiven Israel, therefore Jephthah will forgive. He speaks not with confidence of his success, knowing how justly God might suffer the Ammonites to prevail for the further punishment of Israel. Nor does he speak with any confidence at all in himself. If he succeed, it is the Lord delivers them into his hand; he thereby reminds his countrymen to look up to God as the Giver of victory. The same question as here, in fact, is put to those who desire salvation by Christ. If he save you, will ye be willing that he shall rule you? On no other terms will he save you. If he make you happy, shall he make you holy? If he be your helper, shall he be your Head? Jephthah, to obtain a little worldly honour, was willing to expose his life: shall we be discouraged in our Christian warfare by the difficulties we may meet with, when Christ has promised a crown of life to him that overcometh?
