Some scholars have suggested that Moses would have carried similar tablets down Mount Sinai. The small clay tablets clearly fit the biblical description of small, hand-held slabs, and they were common at the time of Moses. But the production of cuneiform tablets is highly involved: First, it requires a source of good quality, soft clay that can be shaped into tablets. Then the characters are pressed into the clay. The biblical text makes no mention of a source of clay, and, more importantly, the Bible tells us the tablets were made of stone, not clay (Exodus 31:18, 34:1–4).
