Joshua, in his mid-40s, with short, dark hair graying at the temples and a well-trimmed beard, stands on a mountain overlooking the Israelite camp. He wears a simple yet dignified robe of brown and beige, symbolizing his transition into leadership. The desert landscape is vast, and the camp stretches out behind him, with Moses' tent in the background, symbolizing Joshua stepping into his mentor’s role.
