This question is a bit esoteric. Looking at numbers in the Bible I noticed this story about one of Cain's decedents:
And Lamech said to his wives,
“Adah and Zillah, hear my voice;
O wives of Lamech, give ear to my speech.
I have slain a man for wounding me,
And a lad for bruising me.
If Cain is avenged sevenfold,
Then Lamech seventy-sevenfold.”
—Genesis 4:23-24 (NJPS)
Like graded numerical parallelism, the idea of increasing something exponentially is a poetic device. It's a form of hyperbole. But notice that Lamech isn't using a sexagesimal (which would probably produce exaggerated claims of 17- or 67- or 427-fold vengeance), but a decimal numbering system. Since numbers written in cuneiform use a modified base-60 system, does this passage argue against the tablet theory?
