I will tear down the wall you whitewashed and level it to the ground, so that its foundation is exposed. The city will fall, and you will be destroyed within it. Then you will know that I am the LORD.
KJV
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.
ASV
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.
