Charles Ellicott Commentary Luke 19:40

"And he answered and said, I tell you that, if these shall hold their peace, the stones will cry out." — Luke 19:40 (ASV)

If these should hold their peace.—Here, then, at the very moment when He foresaw most clearly His own approaching end, and the failure of all earthly hopes of the city over which He wept, our Lord accepted every word that disciples or multitude had uttered of Him as being in the fullest sense true.

The stones would immediately cry out.—The startling imagery had a precedent in the language of Habakkuk (Habakkuk 2:11), “The stone shall cry out of the wall, and the beam out of the timber shall answer it.”
