Judges 12:5–6

And the Gileadites captured the fords of the Jordan against the Ephraimites. And when any of the fugitives of Ephraim said, “Let me go over,” the men of Gilead said to him, “Are you an Ephraimite?” When he said, “No,” they said to him, “Then say Shibboleth,” and he said, “Sibboleth,” for he could not pronounce it right. Then they seized him and slaughtered him at the fords of the Jordan. At that time 42,000 of the Ephraimites fell.

The Gileadites captured the fords of the Jordan leading to Ephraim, and whenever a survivor of Ephraim said, “Let me cross over,” the men of Gilead asked him, “Are you an Ephraimite?” If he replied, “No,” they said, “All right, say ‘Shibboleth.’ ” If he said, “Sibboleth,” because he could not pronounce the word correctly, they seized him and killed him at the fords of the Jordan. Forty-two thousand Ephraimites were killed at that time.

The Gileadites captured the fords of the Jordan leading to Ephraim. Whenever a fugitive from Ephraim said, “Let me cross over,” the Gileadites asked him, “Are you an Ephraimite?” If he answered, “No,” they told him, “Please say Shibboleth.” If he said, “Sibboleth,” because he could not pronounce it correctly, they seized him and executed him at the fords of the Jordan. At that time forty-two thousand from Ephraim died.

Jephthah captured the shallow crossings of the Jordan River, and whenever a fugitive from Ephraim tried to go back across, the men of Gilead would challenge him. “Are you a member of the tribe of Ephraim?” they would ask. If the man said, “No, I’m not,” they would tell him to say “Shibboleth.” If he was from Ephraim, he would say “Sibboleth,” because people from Ephraim cannot pronounce the word correctly. Then they would take him and kill him at the shallow crossings of the Jordan. In all, 42,000 Ephraimites were killed at that time.

Then Gilead captured the fords of the Jordan from Ephraim, and whenever a fugitive of Ephraim said, “Let me cross over,” the men of Gilead said to him, “Are you an Ephraimite?” When he said, “No,” they said to him, “Please say Shibboleth,” and if he said, “Sibboleth”—because he could not pronounce it correctly—they grabbed him and executed him at the fords of Jordan. At that time forty-two thousand from Ephraim fell.

And the Gileadites took the passages of Jordan before the Ephraimites: and it was so, that when those Ephraimites which were escaped said, Let me go over; that the men of Gilead said unto him, Art thou an Ephraimite? If he said, Nay; Then said they unto him, Say now Shibboleth: and he said Sibboleth: for he could not frame to pronounce it right. Then they took him, and slew him at the passages of Jordan: and there fell at that time of the Ephraimites forty and two thousand.
