Judges 12:4-6

Revised Geneva Translation

⁴ Then Jephthah gathered all the men of Gilead and fought with Ephraim. And the men of Gilead struck Ephraim, because they said, “You Gileadites are fugitives of Ephraim among the Ephraimites and among the Manassites.”

⁵ Also, the Gileadites took the passages of Jordan before the Ephraimites. And when an Ephraimite who had escaped said, “Let me pass,” then the men of Gilead said to him, “Are you an Ephraimite?” If he said, “No,”

⁶ then they said to him, “Say ‘Shibboleth’.” And if he said ‘Sibboleth’ (for he could not pronounce it) then they took him and killed him at the passages of Jordan. And forty-two thousand of the Ephraimites fell at that time.
