And the men of Ephraim gathered themselves together, and went northward, and said unto Jephthah, "Wherefore wentest thou to fight with the children of Ammon, and didst not call us to go with thee? We will therefore burn thine house upon thee with fire." And Jephthah said unto them, "I and my people were at great strife with the children of Ammon. And I called you. But ye delivered me not out of their hands. And when I saw that ye delivered me not, I put my life in my hands and went upon the children of Ammon. And the LORD delivered them into my hands. Wherefore then are ye come upon me to fight with me?" read more.
And Jephthah gathered together all the men of Gilead, and fought with the Ephraimites. And the men of Gilead smote the Ephraimites, because they said, "Ye Gileadites are but renegades of Ephraim among the Ephraimites and the Manassites!" Moreover, the men of Gilead took the passages of Jordan from the Ephraimites. And when those Ephraimites that were escaped said, "Let us go over," then the men of Gilead said unto them, "Ye are Ephraimites." And they said, "Nay." Then the other answered, "Then say, 'Shibboleth.'" And they said, "Syboleth" - and could not so pronounce. Whereupon the others took them and slew them at the passages of Jordan. And there were overthrown at that time, of the Ephraimites, forty two thousand.
