Numbers 14:31-34

³¹And your little ones, whom you said would come into strange hands, I will take in, and they will see the land which you would not have.

³²But as for you, your dead bodies will be stretched in this waste land.

³³And your children will be wanderers in the waste land for forty years, undergoing punishment for your false ways, till your bodies become dust in the waste land.

³⁴And as you went through the land viewing it for forty days, so for forty years, a year for every day, you will undergo punishment for your wrongdoing, and you will see that I am against you.
