Numbers 32:13-15

So the LORD’s anger was aroused against Israel, and He made them wander in the wilderness forty years, until all the generation that had done evil in the sight of the LORD was gone. And look! You have risen in your fathers’ place, a brood of sinful men, to increase still more the fierce anger of the LORD against Israel. For if you turn away from following Him, He will once again leave them in the wilderness, and you will destroy all these people.”
