Numbers 14:30-35

30Except for Caleb the son of Jephunneh and Joshua the son of Nun, not one of you shall enter the land in which I swore [an oath] to settle you.

31But your children whom you said would become plunder, I will bring in, and they will know the land which you have despised and rejected.

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

33Your sons shall be wanderers and shepherds in the wilderness for forty years, and they will suffer for your unfaithfulness (spiritual infidelity), until your corpses are consumed in the wilderness.

34According to the number of days in which you spied out the land [of Canaan], forty days, for each day, you shall bear and suffer a year for your sins and guilt, for forty years, and you shall know My displeasure [the revoking of My promise and My estrangement because of your sin].

35I, the Lord, have spoken. I will most certainly do this to all this evil congregation who are gathered together against Me. In this wilderness they shall be consumed [by war, disease, and plagues], and here they shall die.’ ”
