Parallel
Matthew 24:21
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ἔσται γὰρ τότε θλίψις μεγάλη, οἵα οὐ γέγονεν ἀπ’ ἀρχῆς κόσμου ἕως τοῦ νῦν, οὐδ’ οὐ μὴ γένηται.
For at that time there will be great tribulation, unseen from the beginning of the world until now, and never to be seen again.
