Numbers 32:10-14

Then the LORD was very angry with them, and he vowed, ‘Of all those I rescued from Egypt, no one who is twenty years old or older will ever see the land I swore to give to Abraham, Isaac, and Jacob, for they have not obeyed me wholeheartedly. The only exceptions are Caleb son of Jephunneh the Kenizzite and Joshua son of Nun, for they have wholeheartedly followed the LORD.’ “The LORD was angry with Israel and made them wander in the wilderness for forty years until the entire generation that sinned in the LORD’s sight had died. But here you are, a brood of sinners, doing exactly the same thing! You are making the LORD even angrier with Israel.
