Judges 12:6

“they told him, “Please say Shibboleth.” If he said, “Sibboleth,” because he could not pronounce it correctly, they seized him and killed him at the fords of the Jordan. So at that time 42,000 Ephraimites were killed.”

“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.”

“then said they unto him, Say now Shibboleth; and he said Sibboleth; for he could not frame to pronounce it right: then they laid hold on him, and slew him at the fords of the Jordan. And there fell at that time of Ephraim forty and two thousand.”
