Matthew 24:2

Ὁ δὲ Ἰησοῦς εἶπεν αὐτοῖς, Οὐ βλέπετε πάντα ταῦτα; Ἀμὴν λέγω ὑμῖν, οὐ μὴ ἀφεθῇ ὧδε λίθος ἐπὶ λίθον, ὃς οὐ καταλυθήσεται.

RBT Translation:

Overthrown

And the one who has been separated said to themselves, "Do you not look upon all of these? Trustworthy One, I am saying to yourselves, a stone against stone should not be hurled away in here, whom will not be loosened/overthrown.

καταλύω (katalýō) "to dissolve" or "to destroy." Used to describe the physical destruction of cities and walls, the overthrow of political powers and institutions, and the cessation of activities such as voyages, life, or war. It also means "to dismiss" or "to let go" of people like armies or fleets, and "to loosen" or "to detach" in the context of unharnessing horses or stopping for lodging.

( cf. Strong's #G2647)
