if God did not directly interfere in the lives of the ancient Hebrews, don't you think His Word would have vanished into obscurity? And how would that have fared for the future freewill of humans?
It's seems highly likely to me that you don't understand what "free will" is, either from the Biblical or philosophical perspective....
You DO realize that from the Biblical perpsective, God's Divine Will and Man's Free Will are all there is in the Universe, and are in two different domains, where the expansion of one domain occurs at the cost of contraction of the others? God's Divine Will trumps man's exercise of Free Will, which is another way of saying that whenever God says "thou shalt not", that action is instantly removed from being a matter of exercising man's conscience (Free Will)?
That's another way of saying that God does NOT consider his Divine Will as optional for man to follow: He didn't ask if you wish to comply, and he doesn't give mankind His permission to sin (i.e. defying His Divine Will IS the basic definition of sinning).
And you DO realize that Adam and Eve's original sin WAS to defy his command, taking wisdom from YHWH (in the form of the Forbidden Fruit)? God never intended for man to HAVE free will, since they had to defy Divine Will in order to TAKE the neccessary ingredient that they were missing, in order to exercise free will (wisdom).
