Ezekiel 13:14, 23

And I will break down the wall that you have smeared with whitewash, and bring it down to the ground, so that its foundation will be laid bare. When it falls, you shall perish in the midst of it, and you shall know that I am the LORD.

therefore you shall no more see false visions nor practice divination. I will deliver my people out of your hand. And you shall know that I am the LORD.”
