This illustration is based off of a limestone relief from Susa of a god holding a peg in order to secure the foundation of a temple. This according to Michael Roaf’s book Mesopotamia and the Ancient Near East. A rock is a tiny fragment of a mountain. Mountains were ancient places of worship. Hence the title, “tiny temple”. Perhaps an ancient audience might associate such an image with Jacob’s vision of a temple as he lay his head near a rock. He did set up that very rock as a pillar to mark what he named as God’s house – Bethel.
