Illustrate a scene of a biblical narrative where two Middle Eastern men, representative of Moses and Aaron, gather a diverse crowd consisting of both men and women of various descents like Caucasian, Hispanic, Black, South Asian, and White. They are all dressed in traditional biblical clothing. Aaron is in the act of speaking passionately to the gathered crowd, while Moses stands beside him. Add to the scene a sense of reverence and devotion, in line with Christian teachings. Render this scene in a soft, tender watercolor style, matching the soft textures and hues typical of early 19th century Romanticism. Please note that no text or words should be included in the image.
