And the men of Ephraim gathered themselves together, and went northward, and said unto Jephthah, Wherefore passedst thou over to fight against the children of Ammon, and didst not call us to go with thee? we will burn thine house upon thee with fire.
Gathered themselves together - Hebrew were summoned.
And went northward. After crossing the Jordan, their route from Ephraim was, strict speaking, in a northeasterly direction, toward Mizpeh.
And said unto Jephthah, Wherefore ... thou ... didst not call us. This is a fresh development of the jealous, rash, and irritable temper of the Ephraimites. The ground of their offence now was their desire of enjoying the credit of patriotism, although they had not shared in the glory of victory.
