 And one may investigate from one end of heaven to the other, but one should not investigate what was before this world.Similarly, the Rabbis in a Baraita interpreted to forbid inquiry into the work of creation in the presence of two people, reading the words "for ask now of the days past" to indicate that "one" may inquire, but not "two".The Rabbis reasoned that the words "since the day that God created man upon the earth" in taught that one must not inquire concerning the time before creation.
