Numbers 14:32

30 surely you shall not come into the land concerning which I swore that I would make you dwell therein, except Caleb the son of Jephunneh, and Joshua the son of Nun.

31 But I will bring in your little ones that you said should be captured or killed, and they shall know the land which you have rejected.

32 But as for you, your dead bodies shall fall in this wilderness.

33 Your children shall be wanderers in the wilderness forty years, and shall bear your prostitution, until your dead bodies are consumed in the wilderness.

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