Numbers 14:30-34

You will not enter and occupy the land I swore to give you. The only exceptions will be Caleb son of Jephunneh and Joshua son of Nun. “‘You said your children would be carried off as plunder. Well, I will bring them safely into the land, and they will enjoy what you have despised. But as for you, you will drop dead in this wilderness. And your children will be like shepherds, wandering in the wilderness for forty years. In this way, they will pay for your faithlessness, until the last of you lies dead in the wilderness. “‘Because your men explored the land for forty days, you must wander in the wilderness for forty years—a year for each day, suffering the consequences of your sins. Then you will discover what it is like to have me for an enemy.’
