When Moses asks God (who, the story goes, appears to him in the form of a Burning Bush) "Who are you?", God's reply is :
"I am that I am."
Is God being deliberately tautological here? Is God confused about the distinction between subject and object in sentences? Was the translation really messed up?
Or maybe, God is the only one capable of defining God, so God is self-defining?
Hebrews were not very good in things like Logic or Linguistics.
In fact, they were a tribe of
barbarians nomads whose theology "strangely" had many things in common with Egyptian and other Middle-Eastern religions.
It's the
bBible, not an encyclopedia.
