And the Gileadites took the fords of the Jordan opposite the Ephraimites; and when any of the fugitives of Ephraim said, “Let me cross over,” the men of Gilead would say to him, “Are you an Ephraimite?” If he said, “No,”

they said to him, “Then say ‘Shibboleth.’” And he said, “Sibboleth,” for he could not pronounce it correctly. Then they seized him and killed him at the fords of the Jordan. At that time forty-two thousand of the Ephraimites fell.

Then the Lord said to Gideon, “There are still too many people; bring them down to the water and I will test them for you there. Therefore it shall be that he of whom I say to you, ‘This one shall go with you,’ he shall go with you; but everyone of whom I say to you, ‘This one shall not go with you,’ he shall not go.”
