Numbers 14:29-33

29your dead bodies will fall in this wilderness, even all who were numbered of you, your entire number from twenty years old and upward, who have murmured against Me.

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.
