I also am remiss to mention.. in the Bible and Genesis the "stealing of blessings"

In jubilees and in genesis it says the mother tells to wear Jacob to wear scraps of leather to trick Isaac

According to Jasher she only says to get goats to substitute for the venison, the story in it is very short.

Kinda seems like maybe in these other versions simply the delusion of esau the red hairy hunter boy is what ended up in the text

I might have to double check if I remembered that correctly, but I distinctly recall nothing about the fuzzy leather trick

And also to refresh myself about who is the mother and her history
