'Forty Years' in the Bible

And your children shall wander in the wilderness forty years, and bear your harlotries, until your carcasses are consumed in the wilderness.

After the number of the days in which you searched the land, even forty days, each day for a year, shall you bear your iniquities, even forty years, and you shall know my displeasure.

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