Abe was 75 years old and had a medical problem that needed complicated surgery.
Because his son-in-law Jacob was a renowned surgeon, Abe insisted that Jacob perform the operation.
On the day of his operation, as he lay on the operating table waiting for the anesthetic, Abe asked to speak to his son-in-law.
“Yes, what is it?”
“Don’t be nervous, Jacob, do your best and just remember, if it doesn’t go well, if G-d forbid something should happen to me, your mother-in-law is going to come and live with you for the rest of her life.
