Illustrate a scene inspired by Genesis 36:20 - 'These are the sons of Seir the Horite, who inhabited the land; Lotan, and Shobal, and Zibeon, and Anah'. Picture this in a vivid, highly detailed digital art style. The image consists of four men, each of them distinct in their features and attire. They are posed in an ancient land, against a backdrop of rustic, rugged terrain. Men vary in their mature ages. They have beards and are clothed in traditional Middle-Eastern garbs of the time. Each of them possesses a solemn yet mighty look, reflecting their stature as sons of Seir the Horite.
