Revelation 11:6
Nestle 1904 Greek New Testament · Berean Standard Bible
οὗτοι ἔχουσιν τὴν ἐξουσίαν κλεῖσαι τὸν οὐρανόν ἵνα μὴ ὑετὸς βρέχῃ τὰς ἡμέρας τῆς προφητείας αὐτῶν καὶ ἐξουσίαν ἔχουσιν ἐπὶ τῶν ὑδάτων στρέφειν αὐτὰ εἰς αἷμα καὶ πατάξαι τὴν γῆν ἐν πάσῃ πληγῇ ὁσάκις ἐὰν θελήσωσιν
These witnesses have power to shut the sky so that no rain will fall during the days of their prophecy, and power to turn the waters into blood and to strike the earth with every kind of plague as often as they wish.
