I thought I'd try a little experiment and see if I can demonstrate evidence of evolution of the language in the Old Testament.
Basically, if the history books of Scripture were written during the time period discussed in the text and language evolved over time, then it should be fairly easy to show. If Moses wrote Exodus, for example, and evolution of the language is true, and has been preserved in the Hebrew we have today, then the size of the vocabulary in Exodus should be smaller than the size of the vocabulary in Ezra, for example.
However. if the Documentary Hypothesis is correct, then the entire Old Testament history from Genesis to Esther was written by similarly educated people from the same period of time and should use approximately the same size vocabulary. The null result.
I can think of several other reasons for a null result. Each revision of the language was incorporated into the existing text. Moses was highly educated, so his exceptional language skills mask any actual change in the language over time. The language did not evolve.
But I can't think of any other reasons for a significant positive result, that the size of the vocabulary has changed over time.
Does anyone know if this has been done before?
I am planning to use Strong's Numbers as surrogates for the actual Hebrew words. What problems will this cause?
