Ezekiel 13:14, 23

So will I break down the wall that ye have daubed with untempered mortar, and bring it down to the ground, so that the foundation thereof shall be uncovered; and it shall fall, and ye shall be consumed in the midst thereof: and ye shall know that I am Jehovah.

Therefore ye shall no more see false visions, nor divine divinations: and I will deliver my people out of your hand; and ye shall know that I am Jehovah.
