Waamuzi 12 : 6 Judges chapter 12 verse 6

ndipo wakamwambia, Haya, tamka sasa neno hili, Shibolethi; naye akasema, Sibolethi; kwa maana hakuweza kufanya midomo yake kutamka neno hilo sawasawa; ndipo wakamshika, na kumwua hapo penye vivuko vya Yordani; basi wakaanguka wakati huo watu arobaini na mbili elfu wa Efraimu.
