'Forty Years' in the Bible

And your children shall be wanderers in the wilderness forty years, and shall bear your whoredoms, until your dead bodies be consumed in the wilderness.

After the number of the days in which ye spied out the land, even forty days, for every day a year, shall ye bear your iniquities, even forty years, and ye shall know my alienation.

And Jehovah's anger was kindled against Israel, and he made them wander to and fro in the wilderness forty years, until all the generation, that had done evil in the sight of Jehovah, was consumed.
