Richter 11:7

Jephthah expressed to the elders his astonishment that they had formerly hated and expelled him, and now came to him in their distress, sc., to make him their leader in time of war. Thus he lays his expulsion upon the shoulders of the elders of Gilead, although it was only by his brethren that he had been driven away from his father's house, inasmuch as they had either approved of it, or at all events had not interfered as magistrates to prevent it. We cannot indeed infer from this reproach, that the expulsion and disinheriting of Jephthah was a legal wrong; but so much at all events is implied, namely, that Jephthah looked upon the thing as a wrong that had been done to him, and found the reason in the hatred of his brethren. The Mosaic law contained no regulation upon this matter, since the rule laid down in Deu 21:15-17 simply applied to the sons of different wives, and not to a son by a harlot.

This chapter gives as the history of Jephthah, another of Israel's judges, and numbered among the worthies of the Old Testament, that by faith did great things (Heb 11:32), though he had not such an extraordinary call as the rest there mentioned had. Here we have, I. The disadvantages of his origin (Jdg 11:1-3). II. The Gileadites' choice of him to be commander-in-chief against the Ammonites, and the terms he made with them (Jdg 11:4-11). III. His treaty with the king of Ammon about the rights of the two nations, that the matter might be determined, if possible, without bloodshed (v. 12-28). IV. His war with the Ammonites, which he enters upon with a solemn vow (Jdg 11:29-31), prosecutes with bravery (Jdg 11:32), and ends with a glorious victory (Jdg 11:33). V. The straits he was brought into at his return to his own house by the vow he had made (Jdg 11:34-40).
