SHIBBOLETH
(Shibʹbo·leth) [an ear of grain; or, a stream].
Escaping Ephraimites, during their conflict with Jephthah, gave themselves away to the Gileadite sentries at the fords of the Jordan by mispronouncing the initial “sh” sound of this password. (Judg. 12:4-6) Thus, it is evident that some variation of pronunciation existed among the tribes, even as in later times the Galileans had a manner of speech distinct from the Judeans.—Compare Matthew 26:73; Luke 22:59.
