Samuel
Judges 12:1BSB·traditional attribution

Then the men of Ephraim assembled and crossed the Jordan to Zaphon. They said to Jephthah, “Why have you crossed over to fight the Ammonites without calling us to go with you? We will burn your house down with you inside!”

Matthew Henry Presbyterian @wholebiblehenry

Here Is, I. The unreasonable displeasure of the men of Ephraim against Jephthah, because he had not called them in to his assistance against the Ammonites, that they might share in the triumphs and spoils, Jdg 12:1. Pride was at the bottom of the quarrel. Only by that comes contention. Proud men think all the honours lost that go beside themselves, and then who can stand before envy?

And the men of Ephraim gathered themselves together,.... Or "cried" (r); got together by a cry or proclamation made: in the Hebrew text it is, "a man of Ephraim"; not a single man, but a body of men, who met together and joined as one man. It is highly probable that there were no less than 50,000 of them; for 42,000 of them were slain, Jdg 12:6.

Jdg 12:1-3 Jephthah’s War with the Ephraimites, and Office of Judge. - Jdg 12:1. The jealousy of the tribe of Ephraim, which was striving after the leadership, had already shown itself in the time of Gideon in such a way that nothing but the moderation of that judge averted open hostilities.
