Revelation 10:7

“But in the days of the voice of the seventh angel, when he shall begin to sound, etc.] This is an exception to what the angel had said and swore to, that time should be no longer; “but”, or “unless”, or “except the time of the voice of the seventh angel”, as the Ethiopic version renders it; when a new period and sort of time should begin, very different from the former, which then should be no more; for now will be the time of Christ's kingdom on earth, which shall last a thousand years; this time will not be like the former, a time of darkness and ignorance, as was in some periods, partly through the errors and heresies which were propagated in early times, and through that barbarity and…”

“But--connected with Rev 10:6. "There shall be no longer time (that is, delay), but in the days of the voice of the seventh angel, when he is about to (so the Greek) sound his trumpet (so the Greek), then (literally, 'also'; which conjunction often introduces the consequent member of a sentence) the mystery of God is finished," literally, "has been finished"; the prophet regarding the future as certain as if it were past. A, C, Aleph, and Coptic read the past tense (Greek, "etelesthee"). B reads, as English Version, the future tense (Greek, "telesthee"). "should be finished" (compare Rev 11:15-18). Sweet consolation to the waiting saints! The seventh trumpet shall be sounded without further…”

“But in the days of the voice of the seventh angel - The days in the period of time embraced by the sounding of the seventh trumpet. That is, the affairs of this world would not be consummated in that period embraced in the sounding of the sixth trumpet, but in that embraced in the sounding of the seventh and last of the trumpets. Compare Revelation 11:15-19. When he shall begin to sound - That is, the events referred to will commence at the period when the angel shall begin to sound. It will not be merely during or in that period, but the sounding of the trumpet, and the beginning of those events, will be contemporaneous. In other words, then would commence the reign of righteousness - the…”

“But in the days of the voice of the seventh angel - Who sounded not only at the beginning of those days, but from the beginning to the end. The mystery of God shall be fulfilled - It is said, Rev 17:17, "The word of God shall be fulfilled." The word of God is fulfilled by the destruction of the beast; the mystery, by the removal of the dragon. But these great events are so near together, that they are here mentioned as one. The beginning of them is in heaven, as soon as the seventh trumpet sounds; the end is on the earth and the sea. So long as the third woe remains on the earth and the sea, the mystery of God is not fulfilled. And the angel's swearing is peculiarly for the comfort of holy…”

“10:7 angel blows his trumpet: See 1 Cor 15:51-54; 1 Thes 4:16. • God’s mysterious plan for the world is no surprise; the prophets who served God in the past warned that the day of the Lord would come (see Joel 2:1-3, 10-11; Amos 5:18-20; Zeph 1:14-18).”

“in the: Rev 11:15-18 the mystery: Rom 11:25, Rom 16:25; Eph 3:3-9 as he: Luk 24:44-47; Act 3:21 Revelation 10:8”
