Numbers 14:29-33

29Your bodies will fall in this wilderness—all who were numbered in the census, everyone twenty years of age or older—because you have grumbled against Me.

30Surely none of you will enter the land in which I swore to settle you, except Caleb son of Jephunneh and Joshua son of Nun. 31But I will bring your children, whom you said would become plunder, into the land you have rejected—and they will enjoy it. 32As for you, however, your bodies will fall in this wilderness.

33Your children will be shepherds in the wilderness for forty years, and they will suffer for your unfaithfulness until the last of your bodies lies in the wilderness.
