אוּרִים וְתֻמִּים - Urim and Thummim

The Urim and Thummim must have been two or more small objects that played a crucial role in a legitimate oracular procedure that aimed at determining the will of God. In view of the extra-biblical material, part of which came to light only recently, it seems legitimate to conceive the Urim and the Thummim as differently shaped or differently coloured stones or astragali.
