Judges 12:4 DBY

²  And Jephthah said to them, 'I and my people had a great feud with the Ammonites; and when I called you, you did not deliver me from their hand.

³  And when I saw that you would not deliver me, I took my life in my hand, and crossed over against the Ammonites, and the LORD gave them into my hand; why then have you come up to me this day, to fight against me?'

⁴  Then Jephthah gathered all the men of Gilead and fought with E'phraim; and the men of Gilead smote E'phraim, because they said, 'You are fugitives of E'phraim, you Gileadites, in the midst of E'phraim and Manas'seh.'

⁵  And the Gileadites took the fords of the Jordan against the E'phraimites. And when any of the fugitives of E'phraim said, 'Let me go over,' the men of Gilead said to him, 'Are you an E'phraimite?' When he said, 'No,'

⁶  they said to him, 'Then say Shibboleth,' and he said, 'Sibboleth,' for he could not pronounce it right; then they seized him and slew him at the fords of the Jordan. And there fell at that time forty-two thousand of the E'phraimites.
