Revelation 15:1

“And I saw another sign in heaven, great and marvellous, etc.] This chapter is a preparation to the pouring out of the seven vials, as (<661601>Revelation 16:1-21) is to the sending of the seven epistles, and (<660201>Revelation 2:1-3:22) to the seven seals and seven trumpets: the vision is called a “sign”, because what was seen was significative of future events; a sign of the coming of Christ, of his kingdom, and of the destruction of antichrist; and it is said to be a sign “in heaven”, where John was called up, and where he had his visions; and it was “another”, a different one from that in (<661201>Revelation 12:1) which represented the downfall of Paganism, but this the downfall of…”

“THE LAST SEVEN VIALS OF PLAGUES: SONG OF THE VICTORS OVER THE BEAST. (Rev 15:1-8) the seven last plagues--Greek, "seven plagues which are the last." is filled up--literally, "was finished," or "consummated": the prophetical past for the future, the future being to God as though it were past, so sure of accomplishment is His word. This verse is the summary of the vision that follows: the angels do not actually receive the vials till Rev 15:7; but here, in Rev 15:1, by anticipation they are spoken of as having them. There are no more plagues after these until the Lord's coming in judgment. The destruction of Babylon (Rev 18:2) is the last: then in Rev 19:11-16 He appears.”

“And I saw another sign in heaven - Another wonder or extraordinary symbol. The word “sign” here - σημεῖον sēmeion - is the same which in Revelation 12:1, Revelation 12:3; Revelation 13:13, is rendered “wonder” and “wonders,” and in Revelation 13:14; Revelation 16:14; Revelation 19:20, “miracles.” The word is not found elsewhere in the Book of Revelation, though it is of frequent occurrence in other parts of the New Testament. See it explained in the notes on Revelation 12:1. Here it is used to denote something wonderful or marvelous. This is represented as appearing in heaven, for the judgments that were to fall upon the world were to come thence. Compare Revelation 11:19; Revelation 12:1;…”

“And I saw seven holy angels having the seven last plagues - Before they had the phials, which were as instruments whereby those plagues were to be conveyed. They are termed the last, because by them the wrath of God is fulfilled - Hitherto. God had borne his enemies with much longsuffering; but now his wrath goes forth to the uttermost, pouring plagues on the earth from one end to the other, and round its whole circumference. But, even after these plagues, the holy wrath of God against his other enemies does not cease, Rev 20:15. Revelation 15:2”

“15:1–16:21 The third and final cycle of seven judgments (see study note on 6:1–16:21) is introduced with a vision of God’s victorious people singing a hymn of praise (15:2-4). Then a scene of the Temple is presented (15:5-8), from which angels emerge bearing the bowls of God’s judgment upon the earth (16:1-21). 15:1 This cycle of seven last plagues (15:1–16:21) brings God’s wrath against his enemies to completion (see 16:17; Amos 1–2; Rom 1:18–2:16). Revelation returns later to the subjects of God’s wrath (Rev 19:15-21).”

“I saw: Rev 12:1-3; Dan 4:2, Dan 4:3, Dan 6:27 seven angels: Rev 15:6, Rev 8:2, Rev 8:6, Rev 10:3, 16:1-17, Rev 21:9; Mat 13:41, Mat 13:42, Mat 13:49, Mat 13:50 last: Rev 8:13, Rev 11:14, Rev 16:17-21, Rev 17:1 is filled: Rev 15:7, Rev 14:10, Rev 14:19, Rev 16:19, Rev 19:15; Dan 12:6, Dan 12:7, Dan 12:11, Dan 12:12 Revelation 15:2”
