The rabbi interpreting the text is not claiming direct communication. Most rabbis, in my experience, even admit to human bias in translation and copying.Are you joking? Burning bushes, tablets given to Moses by god, the OT is replete with direct communication by "g-d." A rabbi who said that defition #6 doesn't apply would have to explain how having "g-d" dictate ten commandments and making a covenent doesn't constitute "direct communitcation with the divine."
It is therefore to them an academic exercise in finding the legalistic interpretation of the Torah.
If you do not allow that leeway then I suggest you need to aim your criticism at the entirety of Common Law as their is not rational basis for even the Magna Carta save that it works.
And if you're going to use that defense then you'll have to allow it in the case of chaplains.
