This week's Parshat Shavua, Torah Portion of the Week VaYerah, includes two very disturbing scenes concerning the family life of Avraham's nephew, also protégé, Lot. Both are in Bereishit Genesis Chapter 19.
The first event, which is printed below, takes place when two messengers from Gd, generally translated as angels, who appear to be ordinary men, come to Lot to tell him to take his family and leave Sdom. When neighbors begin to attack the house demanding that Lot hand over the guests for the neighbors to rape, Lot in defense of his guests offers his virgin daughters instead.
Genesis Chapter 19
I consider this offer to be beyond outrageous. We don't read of any protest by his wife or daughters. They are very unlike Avraham's wife Sarah who's not afraid to tell her husband when things need fixing in the family. But most important it prepares us for an equally shocking act by the daughters themselves.
After only Lot and his two daughters manage to escape from Sdom, the girls, believing that they are the last three people on earth, decide to sleep with their father in order to have children. But they didn't tell their father of the plan; they got him drunk, so he was oblivious.
