Parallel
2 Thessalonians 2:4
Nestle 1904 Greek New Testament · Berean Standard Bible
ὁ ἀντικείμενος καὶ ὑπεραιρόμενος ἐπὶ πάντα λεγόμενον Θεὸν ἢ σέβασμα ὥστε αὐτὸν εἰς τὸν ναὸν τοῦ Θεοῦ καθίσαι ἀποδεικνύντα ἑαυτὸν ὅτι ἔστιν Θεός
He will oppose and exalt himself above every so-called god or object of worship. So he will seat himself in the temple of God, proclaiming himself to be God.
