Musar к Ийова 5:16

To summarize: The more a person or a people ascends spiritually the greater the challenge to Satan. Satan will "work overtime" to try and entrap people who are on a spiritual high and to drag them down. People who are about to see their life's wish fulfilled by entering marriage, consecrating a house, or by harvesting the first harvest of their vineyards, are therefore at risk because they have reached a situation close to fulfilment of a major aspiration-similar to that of the Jewish people prior to their entry into the Holy Land. The Rekanati also explains the custom of breaking a glass during the wedding ceremony as a "bribe" to the מדת הדין, much as the proverb about "giving the devil his due." As a result of receiving this recognition, ועולתה קפצה פיה, "the mouth of wrongdoing is stopped" (Job 5,16). When Israel stood at Mount Sinai and received the Torah they were in a state similar to a bride prior to her wedding. Satan exploited this opportunity by making extra efforts to subvert the Jewish people, being afraid that once the tablets became the property of the Jewish people they would forever be immune against his efforts to corrupt them i.e. he would lose his power to hold the threat of mortality over them. By employing the "evil eye," Satan, in the form of the golden calf, succeeded in seducing the nation even though it was on such a high spiritual level.
