Musar zu Bereschit 6:15

According to the Tziyoni, the instruction to Noach to build an ark meant that he was to employ combinations of the letters in G–d's name to do so and to build what could become the equivalent of a Holy Temple. The Tziyoni also quotes the verse from Proverbs about the מגדל עז, that the Zohar discussed. He demonstrates that the letters in G–d's Ineffable Name were manipulated in a manner which enabled Noach to build the ark according to the measurements reported in the Torah.
