Create a scene from the biblical narrative in Exodus 17:11-13. Show a figure representing Moses seated on a stone with his hands held up, assisted by two other figures representing Aaron and Hur, one on each side. Incorporate a distant view of an army, denoting the Israelites, gaining victory in battle, suggesting the scene takes place until sunset. Also represent Joshua overpowering the opposing army, symbolizing the Amalekites, with a sword. Render it in the style of a digital art illustration, considering the bright nuances of twilight and the precise details of the characters and the landscape.
