Create a digital art representation of a figure from biblical times, who can be identified as a religious leader due to his attire and mannerisms, illustrating the concept of Exodus 14:13. The scene should depict this central figure in a calming stance as if conveying the message, 'Do not be afraid. Stand firm and you will see the deliverance the Lord will bring you'. Surround this person with a diverse group of people who appear to be in awe. Capture the essence of traditional biblical art in the surroundings, attire, and general ambiance. Use muted, warm color tones to reflect the historical and sacred context.
