I will not accept answers that bring other sources defending the opinion that Yonasan Ben Uziel indeed wrote this.
I am looking for actual sources that bring theories for its authorship as well as an explanation behind why the source believes that this person could be the author. If an answer does not meet these criteria, it will not be accepted.
I AM NOT LOOKING FOR SOURCES THAT YONASAN BEN UZIEL DIDN’T WRITE IT. I am looking for sources that anybody else wrote it.
