Careful with your timing, though. It’s considered an auspicious place to hold ritual Jewish circumcision, and those don’t involve any anæsthetic except a rag dipped in a bit of wine. Trust me: what is seen and heard cannot be unseen and unheard.

It comes from Genesis 23: "and he said to them, 'if you are willing that I should bury my dead out of my sight, hear me, and entreat for me Ephron the son of Zoar, that he may give me the cave of Machpelah, which he owns... After this Abraham buried Sarah his wife in the cave of the field of Machpelah east of Mamre (that is, Hebron) in the land of Canaan."
According to Targum and the Septuagint, it means "double."
