Depict the biblical moment described in Exodus 12:12, respecting the devotional sentiment towards Christianity. The image should illustrate the potent divine intervention mentioned in the scriptures, using rich colors, intricate detail, and a holy aura. The style should evoke influences from pre-1912 European religious art, filled with symbolism and emotion. Please exclude any text or words from the composition. The medium to consider is the time-honored tradition of oil painting used broadly during the Renaissance period. Remember to incorporate a digital feel in the rendering while still maintaining authenticity in the image.
