Ezekiel 13:14

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

So will I break down the wall that ye have daubed. The repetition of the same threat is to awaken the people out of their dream of safety by the certainty of the event.

So that the foundation thereof shall be discovered. As the "wall" represents the security of the nation, so the "foundation" is Jerusalem, on the fortifications of which they rested their confidence. Grotius makes the "foundation" refer to the false principles on which the rested; supports the former view.
