'Forty Years' in the Bible

And your children shall wander in the wilderness forty years, and bear your whoredoms, until your carcases be wasted in the wilderness.

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

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.
