Richter 11:15

Jephthah Elected as Prince; Negotiations with the Ammonites; Victory, Vow, and Office of Judge - Judges 11-12:7 (Note: On the nature of the sources from which the author drew this tolerably elaborate history of Jephthah, all that can be determined with certainty is, that they sprang from some contemporary of this judge, since they furnish so clear and striking a picture of his life and doings. Bertheau's hypothesis, that the section extending from Jdg 11:12 to Jdg 11:28 is founded upon some historical work, which is also employed in Num 21; Deut 2:1-3:29, and here and there in the book of Joshua, has really no other foundation than the unproved assumption that the Pentateuch and the book of Joshua were written towards the close of the period of the kings. For the marked agreement between Jephthah's negotiations with the king of the Ammonites concerning the possession of the land to the east of the Jordan, and the account given in the Pentateuch, especially in Num 20-21, may be explained very simply and very perfectly, on the supposition that the author possessed the Pentateuch itself. And the account which is wanting in the Pentateuch, namely, that Israel petitioned the king of Moab also for permission to go through his land (Jdg 11:17), may have bee added from oral tradition, as those glorious victories gained by Israel under Moses were celebrated in verse by contemporaneous poets (see Num 21:14, Num 21:17, Num 21:27); and this certainly contributed not a little to keep alive the memory of those events in the nation for centuries long.)

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).
