In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the sources of the watery depths burst open, the floodgates of the sky were opened,

The sources of the watery depths and the floodgates of the sky were closed, and the rain from the sky stopped.
