(The beginning of the Eighth Day)
   Springs of the Great Deep - 2nd month 17th day in Noah’s 600th year.
Genesis 7:11 "In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened."

   It is in this verse that the first occurrence of the Hebrew word chodesh, "month" enters the Scriptures as not one of the descendants of Adam up to Noah ever mentioned it as such. And from this point on in scripture it is used commonly to describe time of events, based on the recurrence of the new moon and the phases of the moon. It’s as if the moon appeared during the Flood, and may have even been the cause of the Flood due to its interaction with the earth.
