I know that somewhere in something I have read there is a comment that someone (Yaakov avinu?) was so spiritually pure/holy that his soul did not cling to the earthly shell that was his body but came out with no resistance. The image was that of drawing an eyelash from a bowl of milk.
I think. I certainly don't think I could make up that image.
The problem is I can't remember who said it, where I read it or about whom. A web search of relevant terms didn't quickly turn anything up. The Stone Chumash (when discussing Yaakov) likens the death as "removing a coat" but that's not the visual I'm looking for.
I'm wondering if anyone recognizes the reference and can help me with a source. I don't mean this as a riddle or a scavenger hunt -- I would really like this source for a discussion I am having elsewhere.
