Parshas Noach: Noach Was Destined To See Destruction
"Eileh Toldos Noach, Noach." The Rokeach says that the reason it says Noach's name twice is because he saw two Churbonos in his lifetime, the Mabul and the Dor Haflaga. Rav Moshe Singer points out that the gematria of the two words HaMabul and Haflaga equal 206 which is the same value as the words Noach Noach in "Al Bam" (Aleph Lamed, Bais Mem, Gimmel Nun,...).
Additionally, the letters of Noach, Nun and Ches, are the first letters in the words Nehi Churban, wailing and destruction, which he unfortunately experienced twice in his life, once wiping life off the face of the earth, and once dispersing mankind all over the face of the earth. Quite contrary to the plain meaning of his name.
