Judges 11:4
And it came to pass in process of time, that the children of Ammon made war against Israel.
And it came to pass in process of time,.... Some time after Jephthah had been expelled from his father's house, and he was become famous for his martial genius, and military exploits; or at the close of the eighteen years' oppression of the children of Israel by the Ammonites, or some few days after the children of Israel were gathered together at Mizpeh, that the people and princes of Gilead were preparing for war with Ammon, and were thinking of a proper person to be their general:
that the children of Ammon made war against Israel; not only passed over Jordan again, and encamped in Gilead, but began to attack them in some place or another, at least threatened them with it, and made motions towards it.
