John Calvin Commentary Ezekiel 13:15

"Thus will I accomplish my wrath upon the wall, and upon them that have daubed it with untempered [mortar]; and I will say unto you, The wall is no more, neither they that daubed it;" — Ezekiel 13:15 (ASV)

If the deep-rooted obstinacy of the people had not been known to us, Ezekiel would seem too wordy, since he might have said in a few words what he explains at such length. But if we bear in mind the perverse and rebellious nature of the people, we will find that there was need of such constant repetition: I will fulfill, he says, my burning wrath upon the wall; that is, I will show how detestable and destructive this doctrine was to my people.

Hence God accomplished His anger on the wall when He reduced to nothing all the lies of the false prophets. Afterwards, He also attacked them, since the mark of disgrace was attached to their characters, and this rendered their doctrine detestable. Afterwards, He says, I will say, There is no wall; those who daubed it are not.

When God speaks this way, He means that He will allow the false prophets to triumph among the people for only a short time. For even up to the destruction of the city and temple, they always withstood God’s servants with a bold forehead, as if they would thrust their horns against God and His pronouncements. Let us observe, then, that while Jerusalem was standing, the appearance of a wall existed, for there was the support of false doctrine, and the people fed willingly on such deceits. Their daubing, therefore, stood until it vanished with the ruin of the city, and then their futility was exposed, for God took vengeance on these insolent triflers.
