'Forty Days' in the Bible

When I went up into the mountain to receive the tables of stone - the tables of the covenant, which Yahweh had solemnised with you, then abode I in the mountain forty days and forty nights, food, did I not, eat, and water, did I not drink.

So then it came to pass at the end of forty days and forty nights, that Yahweh gave unto me the two tables of stone the tables of the covenant.

Then lay I prostrate before Yahweh as at the first, forty days and forty nights, food, did I not eat, and water, did I not drink, - because of all your sin which ye had sinned, in doing the thing that was wicked, in the eyes of Yahweh. to provoke him to anger.

Thus, then lay I prostrate before Yahweh, the forty days and the forty nights that I did lie prostrate, - because Yahweh spake of destroying you.

But, I, stayed in the mountain according to the former days, forty days and forty nights, - and Yahweh hearkened unto me at that time also, Yahweh was not willing a to destroy thee.
