So the Pharoah was boffing Abraham’s hot wife because Abraham told her to lie that she wasn’t his wife, but rather his sister? And he basically gave her away because he was scared of getting killed if they knew she was his wife? Wow.
By the way, how did the 75-year old Abraham end up with a hot wife anyway?
No, the Pharoah didn’t boff her. He couldn’t....he was ill. But to make a long explanation short......
Yes, as a rule back then, had the Pharaoh known that Sarah was his wife, he would have killed Abraham. However, he would not have killed her brother.
No, he did not give her away. The Egyptian princes took her away from Abraham, but Abraham and Sarah knew that Pharoah was going to get a nasty sickness.
G-D had told him that the Pharoah was stricken with the plague of Ra’athan, making intercourse painful and harmful to him. Gen. Rabbah (41:2).
So it bought them time....
