this is a good example of why the apocrypha are worth looking at

the detail in Jasher about this exact situation illuminates a lot... and Enoch also mentions his Red Hair and White Skin

and no coincidence, probably that Esau exhibits these physical characteristics, i'm sure i don't have to remind you of the Jacob and Esau and their mother and the furry Esau scenario... interestingly, in Jasher, the conniving part of the mother's actions are missing! 

honestly, on the face of it the plain Genesis version makes Jacob look bad, instead of suggestible, and his mother seems like a straight up Eve

i honestly can't make sense of teh story even with 3 different versions, it still seems shady to me but in all three versions the further actions of Esau make it very clear this guy was a piece of shit
