Cyrill of Alexandria
Because you have deceitfully administered falsehood to the people, leading them into a state of confusion and indulgence, while falsely assuring them of peace, you have rendered them vulnerable to the destruction of conflict. Therefore, justly shall night and darkness envelop you, even as you claim to possess insight and strive to predict accurately. The sun shall set upon you, and the very radiance of day shall be turned into gloom. This does not imply that the physical sun indeed withdraws its rays from you, nor that dawn's light is truly extinguished.

Rather, the magnitude of your calamity represents a profound darkness, a night that is impenetrable, akin to the withdrawal of the sun's brightness and the concealment of light; for severe and extraordinary misfortunes bewilder the mind, unsettle the heart, and enshroud it in darkness.
It may rightly be observed that the spiritual light has also been obscured for the Jewish people who acted defiantly against Christ, as God does not shine upon them, leaving them devoid of spiritual illumination. It is akin to being enveloped in the night of sin, as it is written, "they were blinded," for as Paul states, "when Moses is read, a veil is laid over their heart" (2 Cor. 3:14-15); "when they claim wisdom, they become foolish, and their foolish hearts are darkened" (Rom. 1:21-22). Christ predicted this consequence, urging, "Wherefore ye have light, walk in the light, that ye may be sons of light" (John 12:36). However, in rejecting the divine light, that is, Christ, they find themselves shrouded in darkness, with "the night filled with visions," as the prophet proclaimed.
A similar fate awaits the purveyors of heresies, who, under the guise of insight and while attempting to grasp the mystery of Christ, propagate falsehoods and the detrimental effects of their delusions, much like droplets tainting the hearts of the unsuspecting, thereby steering them away from the doctrines of truth. Hence, "night and darkness shall be upon them from the vision," and they shall be cast into obscurity, having sinned against their fellow believers and crushing the delicate consciences of those for whom Christ sacrificed Himself (1 Cor. 8:12-13).
