And the elders of Gilead said unto Jephthah,.... Assenting to his proposal, and not only giving their word for it, but their oath:

the Lord be witness between us, if we do not so according to thy words; that is, make him head over them; they appealed to the omniscient God, and called on him to be a witness of their agreement to it, and swore by him they would fulfil it; or if they did not, that the Lord would take vengeance on them for it, and punish the breach of this covenant and oath in some way or another; the Targum of Jonathan is,"the Word of the Lord be a witness between us, &c.''

The elders promised this on oath. "Jehovah be hearing between us," i.e., be hearer and judge of the things concerning which we are negotiating; "truly according to thy word so will we do" (לא אם, a particle used in connection with an oath).

And the elders of Gilead said unto Jephthah, The LORD be witness between us, if we do not so according to thy words.

11:10 The Lord be witness - The Lord be an hearer: so the Hebrew word is. Whatever we speak it concerns us to remember, that God is an hearer!

witness...: Heb. the hearer between us

10, 11. the elders of Israel said unto Jephthah, The Lord be witness between us-Their offer being accompanied by the most solemn oath, Jephthah intimated his acceptance of the mission, and his willingness to accompany them. But to make "assurance doubly sure," he took care that the pledge given by the deputies in Tob should be ratified in a general assembly of the people at Mizpeh; and the language of the historian, "Jephthah uttered all his words before the Lord," seems to imply that his inauguration with the character and extraordinary office of judge was solemnized by prayer for the divine blessing, or some religious ceremonial.

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?
