'Windows of Heaven' in the Bible

In the six hundredth year of Noah's life, in the second month, in the seventeenth day of the month, that same day were all the fountains of the great deep broken up, and the windows of heaven were opened,

and the fountains of the deep and the windows of heaven were stopped, and the rain of heaven was forbidden,

Bring every tithe into my barn, that there may be meat in mine house: and prove me withal, sayeth the LORD of Hosts, if I will not open the windows of heaven unto you, and pour you out a blessing with plenteousness.
