2 Thessalonians 2:4
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ὁ ἀντικείμενος καὶ ὑπεραιρόμενος ἐπὶ πάντα λεγόμενον Θεὸν ἢ σέβασμα, ὥστε αὐτὸν εἰς τὸν ναὸν τοῦ Θεοῦ ὡς Θεὸν καθίσαι, ἀποδεικνύντα ἑαυτὸν ὅτι ἐστὶ 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.
