Numbers 32:11-13

11‘Because they did not follow Me wholeheartedly, not one of the men twenty years of age or older who came out of Egypt will see the land that I swore to give Abraham, Isaac, and Jacob— 12not one except Caleb son of Jephunneh the Kenizzite and Joshua son of Nun—because they did follow the LORD wholeheartedly.’ 13The anger of the LORD burned against Israel, and He made them wander in the wilderness forty years, until the whole generation who had done evil in His sight was gone.
