Numbers 32:11-13

11‘Because they have not followed me wholeheartedly, not one of the men twenty years old and upward who came from Egypt will see the land that I swore to give to Abraham, Isaac, and Jacob,

12except Caleb son of Jephunneh the Kenizzite, and Joshua son of Nun, for they followed the Lord wholeheartedly.’

13So the Lord’s anger was kindled against the Israelites, and he made them wander in the wilderness for forty years, until all that generation that had done wickedly before the Lord was finished.
