8:2 And I saw the seven angels who stand before God; and seven trumpets were given to them.

And I saw the seven angels who stand before God;

Again, John is very precise when he uses 'the seven angels'; these seven angels are 'presence angels' and most likely are the same as the archangels. We know of two of them in our scriptures, while Jewish writings indicate the remaining five as shown in the following table.

Offering up of the prayers of the saints in Jewish thought is connected with archangels.

and seven trumpets were given to them.

In Israel, the trumpet warned of danger. In Zephaniah 1:14-18, it warns of the last days. See also Numbers 10:1-10 and Joel 2:1-2.

Before every woe, a warning is given by an angel blowing a trumpet. Each trumpet was unique and contained its own warning upon a specific part of the physical universe.

Trumpets also are associated with revelation particularly the giving of the Law (Exodus 19:16-20) and the prophesy (Amos 3:6-7). Jericho prevented Israel from taking the Promised Land; it fell by the trumpet (Joshua 6:12-21); so, too, the evil one prevents or tries to prevent Christ from claiming His true inheritance. This is associated with seal seven. Satan uses the Gentile nations to hold on to this earth and to fight the Jews, God's Chosen. See Zechariah 14:1-4 and Luke 21:20-24.

BUT GOD WILL OVERCOME! Isaiah 51:21-23, Isaiah 26:20-21, Isaiah 35:3-4, Zechariah 6:9-15, and Zechariah 13:7-9.
