A few of us have been thinking the same thing about there being a mole in the house.
When I was looking up Esau the other day I found;
"Jacob impersonates his hairy older twin by dressing in Esau's clothes"
So that makes me think a little bit like we the public are Jacob & Esau is the mole housemate we control?
Also it could mean a house divide? Jacob/Isreal - Esau/Palestine.
Can't see it really though, just a guess
