This fact establishes every word of what Jephthah stated here as absolutely accurate and is also a glorious proof of the fact that the Pentateuch existed many, many years before the Book of Judges.  As we have often pointed out, nothing is any more erroneous and ridiculous than is the radical critical dictum that the Pentateuch did not exist until the times of Josiah.  That "fairy tale" is comparable only to those of Hans Christian Andersen.
