Numbers 14:33-35

33Your children will be shepherds in the wilderness for forty years and bear the penalty for your acts of unfaithfulness until all your corpses lie scattered in the wilderness.

34You will bear the consequences of your iniquities forty years based on the number of the forty days that you scouted the land, a year for each day. You will know my displeasure.

35I, the Lord, have spoken. I swear that I will do this to the entire evil community that has conspired against me. They will come to an end in the wilderness, and there they will die.”
