Yahweh-worship was famously aniconic, meaning that the god was not depicted by a statue or other image. This is not to say that he was not represented in some symbolic form, and early Israelite worship probably focused on standing stones, but according to the Biblical texts the temple in Jerusalem featured Yahweh's throne in the form of two cherubim, their inner wings forming the seat and a box (the Ark of the Covenant) as a footstool, while the throne itself was empty. No satisfactory explanation of Israelite aniconism has been advanced, and a number of recent scholars have argued that Yahweh was in fact represented prior to the reforms of Hezekiah and Josiah late in the monarchic period: to quote one recent study, "n early aniconism, "de facto" or otherwise, is purely a projection of the post-exilic imagination" (MacDonald, 2007).
