Ezekiel 13:14, 23

So I will tear down the wall which you have plastered with whitewash and bring it down to the ground, so that its foundations will be exposed; when it falls, you will perish in its midst. And you shall know and understand fully that I am the LORD.

therefore, you women will no longer see false visions or practice divinations, and I will rescue My people from your hand. Then you will know [without any doubt] that I am the LORD.”
