Genesis 7:11-13

New Century Version

¹¹ When Noah was six hundred years old, the flood started. On the seventeenth day of the second month of that year the underground springs split open, and the clouds in the sky poured out rain. ¹² The rain fell on the earth for forty days and forty nights.

¹³ On that same day Noah and his wife, his sons Shem, Ham, and Japheth, and their wives went into the boat.
