Numbers 32:13-15

And the LORD’s anger was kindled 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 behold, 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 again abandon them in the wilderness, and you will destroy all this people.”
