דניאל, פרק ז׳, פסוק כ״ה

A dark vision unfolds of a future tyrant rising to power, intent on crushing both faith and the faithful. This oppressive ruler directs his arrogance toward the heavens, speaking words of severe blasphemy and insult against God [רש״י, מצודת דוד, שטיינזלץ]. His cruelty extends from heaven to earth, specifically targeting the holy ones. These individuals are identified as the people of Israel [רש״י, מצודת דוד], or more specifically, the righteous among them [מלבי״ם]. The tyrant will systematically harass, oppress, and grind them down. Historically, this period of persecution is identified by some with the rise and spread of Islam, under whose dominion the majority of the exiled Jewish people found themselves [מצודת דוד, מלבי״ם].

Beyond physical oppression, the ruler engages in calculated spiritual warfare. He carefully plots to uproot the laws of the Torah and force the people of Israel to abandon their faith. His ultimate goal is to fundamentally alter the sacred calendar, seeking to abolish the established festivals and the Sabbaths [רש״י, מצודת דוד, שטיינזלץ].

However, this reign of terror is not permanent; it is restricted to a mysterious, pre-determined timeframe. The primary approach among commentators is that this designated period represents a hidden calculation regarding the End of Days [רש״י], though they differ on how to decode it. One perspective takes the timeframe literally, suggesting a brief and intense period of two and a half years during which the people of Israel will be entirely subjected to the tyrant's power [מצודת דוד].

Conversely, others interpret this timeframe as a complex code for much longer historical eras. One calculation defines a unit of time by combining the years from the Exodus from Egypt with the duration of the First Temple. Together with the remaining half-measure, this totals one thousand three hundred and thirty-five years, beginning from the moment the daily Temple sacrifice was abolished [רש״י בשם רב סעדיה גאון]. Another approach views a unit of time as a foundational historical era, such as the four hundred years of the Egyptian exile or the four hundred and ten years of the First Temple. According to this view, the total period consists of three and a half of these units, ultimately pointing to the exact moment when the long exile will finally come to an end [מלבי״ם].
