Numbers 14:30

26 Then the LORD said to Moses and Aaron,

27 “How long will this wicked congregation grumble against Me? I have heard the complaints that the Israelites are making against Me.

28 So tell them: As surely as I live, declares the LORD, I will do to you exactly as I heard you say.

29 Your 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.

30 Surely none of you will enter the land in which I swore to settle you, except Caleb son of Jephunneh and Joshua son of Nun.

31 But I will bring your children, whom you said would become plunder, into the land you have rejected—and they will enjoy it.

32 As for you, however, your bodies will fall in this wilderness.

33 Your 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.

34 In keeping with the forty days you spied out the land, you shall bear your guilt forty years—a year for each day—and you will experience My alienation.
