You've just got to have the tablets of stone if you want to have fun with the Old Testament. These were made from 2" styrofoam, splattered with joint compound and painted with a couple different colors of spray paint. The letters are block Hebrew (not accurate to the period but I thought they looked cooler) and were carved into the "stone" with an Exacto knife and painted black.

I got the Hebrew from a painting (I think it was in the Boston Public Library) and may not have transcribed it completely accurately - but it looks good for a prop.
