A dramatic biblical scene inspired by Exodus 10:21. Depict Moses, an older Middle Eastern man with a flowing white beard and wearing traditional attire, as he extends his arm towards the vast sky. The atmosphere is eerie, suggesting an impending event. An oppressive darkness, tangible and ominous, begins to spread over the land of Egypt, shrouding cities, pyramids, and the Nile in its embrace. The scene is filled with uncanny anticipation and dread, capturing the pivotal moment described in the scripture. The visual style should lean towards the aesthetics of pre-1912 traditional styles, using a digital medium.
