A devotional and respectful tale from Exodus 8:1-15 depicted in a watercolor medium. Envision a biblical figure, raising his staff towards the heavens as innumerable frogs rain down onto the land and water bodies below. The people around look on in awe and disbelief. The architecture and attire should adhere to historical records of the era. Create this scene with a gentle color palette to portray the essence of the story, in a respectful and devotional manner towards Christianity.
