Numbers 14:22, 33, 34

not one of those who saw my glory and the signs I performed in Egypt and in the wilderness but who disobeyed me and tested me ten times

Your children will be shepherds here for forty years, suffering for your unfaithfulness, until the last of your bodies lies in the wilderness.

For forty years—one year for each of the forty days you explored the land—you will suffer for your sins and know what it is like to have me against you.’
