'Forty Days' in the Bible

for after other seven days I am sending rain on the earth forty days and forty nights, and have wiped away all the substance that I have made from off the face of the ground.'

and the shower is on the earth forty days and forty nights.

And the deluge is forty days on the earth, and the waters multiply, and lift up the ark, and it is raised up from off the earth;

And it cometh to pass, at the end of forty days, that Noah openeth the window of the ark which he made,

and they fulfil for him forty days, for so they fulfil the days of the embalmed, and the Egyptians weep for him seventy days.
