Judges 11:4 Meaning and Commentary

Judges 11:4

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.

Judges 11:4 In-Context

2 And the wife of Galaad bore him sons; and the sons of his wife grew up, and they cast out Jephthae, and said to him, Thou shalt not inherit in the house of our father, for thou art the son of a concubine.
3 And Jephthae fled from the face of his brethren, and dwelt in the land of Tob; and vain men gathered to Jephthae, and went out with him.
4 And it came to pass when the children of Ammon prepared to fight with Israel,
5 that the elders of Galaad went to fetch Jephthae from the land of Tob.
6 And they said to Jephthae, Come, and be our head, and we will fight with the sons of Ammon.
