Revelation 10:7
Nestle 1904 Greek New Testament · Berean Standard Bible
ἀλλ’ ἐν ταῖς ἡμέραις τῆς φωνῆς τοῦ ἑβδόμου ἀγγέλου ὅταν μέλλῃ σαλπίζειν καὶ ἐτελέσθη τὸ μυστήριον τοῦ Θεοῦ ὡς εὐηγγέλισεν τοὺς ἑαυτοῦ δούλους τοὺς προφήτας
But in the days of the voice of the seventh angel, when he begins to sound his trumpet, the mystery of God will be fulfilled, just as He proclaimed to His servants the prophets.”
