Why did Lot's daughters have relations with their father?
1Do you have some reason to suspect they shouldn't have?– Double AA ♦Nov 4, 2014 at 22:02
@DoubleAA Don't expect an answer anytime soon -- this account is unregistered, and hasn't been active since 2011 :P [ presumably, the reason to assume they shouldn't is because it is forbidden, and generally considered to be weird ]– MTLNov 4, 2014 at 22:05
19:31 seems clear enough. Why is this a question? (There may be other reasons, of course, but it's not as if the text is silent on the subject.)– Monica CellioNov 5, 2014 at 2:20
- They thought there was no one left in the World (ibn Ezra and ibn Kaspi, Rashi and Rashbam)
- Radak says they thought no one would marry them since they came from the destroyed cities they would be outcasts
- Seforno has the most intriguing answer -- they held themselves to have a great Yichus and there was no one good enough left to marry.
