Genesis 7:11-12; Genesis 7:23

11 On the seventeenth day of the second month of the 600th year of Noach's life all the fountains of the great deep were broken up, and the windows of the sky were opened.

12 It rained on the earth forty days and forty nights.

23 He wiped out every living thing on the surface of the ground - not only human beings, but livestock, creeping animals and birds in the air. They were wiped out from the earth; only Noach was left, along with those who were with him in the ark.
