'Forty Years' in the Bible

And your sons shall feed in the wilderness forty years and bear your fornications, until your dead bodies have wasted in the wilderness.

According to the number of the days in which you searched the land, forty days, each day for a year you shall bear your iniquities, forty years; and you shall know My alienation.

And Jehovah's anger was kindled against Israel, and He made them wander in the wilderness forty years until all the generation which had done evil in the sight of Jehovah was destroyed.
