Parallel
Matthew 24:21
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ἔσται γὰρ τότε θλῖψις 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.
