Numbers 14:33-35

33Your children will be shepherds in the desert for 40 years. Because you did not trust me, your children will have trouble. That will continue until all your dead bodies are lying in the desert.

34You explored the land of Canaan for 40 days. Now you will have trouble for 40 years, because of your sins. Each day becomes one year! You will know that I am not with you, but I am against you.

35I, the Lord, have spoken! I will certainly do all these things to punish these evil people. That is because they have all joined together to speak against me. In this desert they will die. Yes, that will be the end of them!” ’
