Basil of Caesarea — as excerpted in the Catena Aurea on Luke 20:9-18

“And this happens as it were to men who are condemned, having nothing to answer to the plain evidence of justice. But it is the property of Divine mercy not to inflict punishment in secret, but to foretell it with threatenings, that so it might recall men to repentance; and thus it follows here, He shall come and destroy those husbandmen.”
