Judges 12:6
Brenton's English Septuagint · Berean Standard Bible
Then they said to him, Say now Stachys; and he did not rightly pronounce it so: and they took him, and slew him at the fords of Jordan; and there fell at that time of Ephraim two and forty thousand.
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.
