Create an image illustrating a Biblical scene from Genesis 13:18: a Middle Eastern man, Abram, dismantling his tent in the vast desert. He proceeds to settle in the expansive plain of Mamre, located within Hebron. Note the arid sands, scattered vegetation, and hazy horizon of the landscape. In this new location, he erects an altar dedicated to a higher power. Capture this scene as a digital art piece, emphasizing the sheer scale of the environment and the juxtaposition of humanity within nature.
