Sorry but there is no evidence biblical or otherwise that god spoke hebrew in any form
this may help you though

the fact is hebrew is a language derived from pro-semitic with lots of changes
language shows that there was never one language,people just thought thiers was the first
2nd. - Is there evidence that the major part of the principal languages which derived from the mixing of a first and complete Ancient Hebrew Language did not abide any phoneme similar to the J sound as it is spoken in either French, Italian or English?
there isn't any evidence of this, if the language shows no sign of a consenint anywhere in any other related languages then i doubt it ever existed
