E poi ch'il re ebbe veduta la regina Ester stante nel cortile, essa incontrò grazia agli occhi suoi, ed il re stese verso Ester la verga d'oro che aveva in mano, ed Ester s'avvicinò, e toccò la cima della verga.

לא יסור שבט מיהודה, the ruler is called שבט because he exercises authority over the people and disciplines them if they disobey. He uses his power like a father uses his rod on a disobedient son. In fact, the rod or scepter, or its equivalent, are carried by people in authority in order to remind those who are subservient to them as a symbol of their power to exact punishment. We find such a שבט called שרביט הזהב, “the golden scepter,” and whether the king extended it or failed to extend it to a supplicant determined if he would be executed. (Esther 5,2) The expression also occurs in the sense we have mentioned in Isaiah 14,5 and in Psalms 45,7.
