Defining a Palestinian Authorship

Some people favor an alexandrian authorship because jude is going to dip intothe of enoch. Neghborgd and his comar, the epistles of pete have urged a palestinian origin. Other evidence points to a pesur type excesus practised by jude which suggests close ties with pales time. It's not clear to me at all t that jude is using a pessure technique. But that doesn't mean it wasn't written in Judea or palestine either.
