Genesis 7:10-12

Amplified Bible

¹⁰ And after the seven days [God released the rain and] the floodwaters came on the earth. ¹¹ In the six hundredth year of Noah’s life, on the seventeenth day of the second month, on that same day all the fountains of the great deep [subterranean waters] burst open, and the windows and floodgates of the heavens were opened. ¹² It rained on the earth for forty days and forty nights.
