Barbara Pfeffer Billauer asked:
If a couple as one set of identical twins (boys) is the mitzvah of Pru or Revu satisfied?
Thank you,
Barbara Pfeffer Billauer
The Kollel replies:
The Mitzvah of Pru u'Revu is not satisfied because the Halachah follows Beit Hillel, who rules that one is required to beget a boy and a girl.
All the best,
Dovid Bloom
