Depict an ancient battle scene in the vale of Siddim, as described in Genesis 14:8. It illustrates five kings, representing the cities of Sodom, Gomorrah, Admah, Zeboiim, and Bela (also known as Zoar) joining into battle. Each king should have a distinguishable emblem or symbol representative of their city. Set this in a lush valley (vale), with the kings prominently positioned against a dramatic sky. The style should resemble early Renaissance, emphasizing attention to detail, realism, and depth. The atmosphere should convey respect and devotion to Christianity. Ensure there are no textual elements in the image.
