Bible Verses About The River Jordan: Slaughter of the Ephraimites

Then Yiftach gathered together all the men of Gil'ad and fought with Efrayim, and the men of Gil'ad defeated Efrayim; because they were saying, "You Gil'ad men who live in Efrayim and M'nasheh have deserted Efrayim!"

The men of Gil'ad cut off Efrayim from the crossings over the Yarden, and whenever anyone from Efrayim tried to escape and said, "Let me go across," the men of Gil'ad would ask him, "Are you from Efrayim?" and if he said, "No,"

they would tell him to say "Shibbolet." If he said, "Sibbolet," because he could not make his mouth pronounce it right, they took hold of him and killed him on the spot at the Yarden crossing; at that time 42,000 men of Efrayim died.
