John Gill Commentary Ezekiel 13:12

"Lo, when the wall is fallen, shall it not be said unto you, Where is the daubing wherewith ye have daubed it?" — Ezekiel 13:12 (ASV)

Lo, when the wall is fallen, Jerusalem is taken: shall it not be said to you, the false prophets, by the people who had been deceived by them: where [is] the daubing with which you have daubed [it]? what is become of all your promises of peace, and assurance of safety and prosperity; your smooth words and plausible arguments; your specious pretences, and flattering prophecies? thus would they be insulted by those they had deceived, as well as laughed at by such who disregarded their predictions, and believed the prophets of the Lord.
