When my (now 23-year old Marine) firstborn son was a little boy, I told him about the Exodus, repeatedly emphasizing that the water was "like a wall to their right and to their left." He was skipping along with me one day when he was about age 5, going across a muddy area, and he was grabbing invisible "somethings" out of the air and putting them in a little basket he was carrying.
"What are you doing, Ben?"
"Picking fishes out of the wall."
Love it! Thanks for sharing that.
