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?And the elders of Gilead said unto Jephthah,.... In reply to his objection:

therefore we turn again unto thee now; being sensible of the injury they had done him, and repenting of it, of which their return to him was an evidence; it being with this view to remove the disgrace and dishonour that had been cast upon him, by conferring such honour on him, as to be their chief ruler:

that thou mayest go with us, and fight against the children of Ammon, and be our head over all the inhabitants of Gilead; the end of their coming to him was not only to bring him back with them to his own country, and to fight against the Ammonites, and the defence of it, but to be the sole governor of it; not of all Israel, but of the tribes beyond Jordan, which inhabited the land of Gilead: more than this they could not promise, though he afterwards was judge over all Israel, notwithstanding there was a law in Israel, that no spurious person should enter into the congregation, or bear any public office; so it was a law with the Athenians (i), that unless a man was born of both parents citizens, he should be reckoned spurious, and have no share in the government, see Judges 11:2.
