Rashbam on Deuteronomy

Sforno on Deuteronomy
תמונת כל סמל, something that would reflect the belief of those who hold that every perishable, ephemeral phenomenon in this world has a counterpart in the celestial regions which it is derived from, and that people made themselves replicas of what they thought the original looked like.
