Shibboleth

Holman Bible Dictionary

(sshihb' boh lehth) Transliteration of Hebrew password meaning, “ears, twigs” or “brook.” People of Gilead east of the Jordan used it to detect people of Ephraim from west of the Jordan since the Ephraimite dialect evidently did not include the sh sound, so Ephraimites always said, “sibboleth,” a word not used elsewhere in Hebrew ( Judges 12:6 ).
