I like #19 the best.
It reminds me of what a scared animal does as it’s eating. His eyes are aware of things moving and he seems scared, and ready to head for cover.
From the most powerful man in the known World, to a cowardly lamb hiding from all that could be dangerous to him.
He was truly lowered by the Almighty, and knew it.
Don't know if you've ever noticed--most people haven't--but prey animals' eyes are on the sides of their heads for greater peripheral vision, because of their need for constant vigilance, as you suggested; whereas predators' eyes both face straight ahead, to aid in hunting. Ergo, we are predatory.
