Revelation 8:3
1 Now when the Lamb opened the seventh seal there was silence in heaven for about half an hour. 2 Then I saw the seven angels who stand before God, and seven trumpets were given to them. 3 Another angel holding a golden censer came and was stationed at the altar. A large amount of incense was given to him to offer up, with the prayers of all the saints, on the golden altar that is before the throne. 4 The smoke coming from the incense, along with the prayers of the saints, ascended before God from the angel’s hand. 5 Then the angel took the censer, filled it with fire from the altar, and threw it on the earth, and there were crashes of thunder, roaring, flashes of lightning, and an earthquake.
3 Baruch 12
Greek Apocalypse of Baruch1, And as I was conversing with them, behold angels came bearing baskets full of flowers. And 2 they gave them to Michael. And I asked the angel, Lord, who are these, and what are the things 3 brought hither from beside them? And he said to me, These are angels (who) are over the 4 righteous. And the archangel took the baskets, and cast them into the vessel. And the angel 5 said to me, These flowers are the merits of the righteous. And I saw other angels bearing baskets which were (neither) empty-nor full. And they began to lament, and did not venture to draw near, 6 because they had not the prizes complete. And Michael cried and said, Come hither, also, ye 7 angels, bring what ye have brought. And Michael was exceedingly grieved, and the angel who was with me, because they did not fill the vessel.
Notes and References
"... It is well known that in the centuries prior to the turn of the eras, the angelology and demonology of Judaism underwent considerable development and we find in the apocalyptic texts a rather complex set of ideas relating to these opposing angelic groups. The order of holy angels is arranged according to a strict hierarchy and each class of angel has its set function. To choose only a few examples, there are angels responsible for the natural elements and astral phenomena (compare 1 Enoch 60:11-23; 2 Enoch 4:1-6:1; 19:2-6; Jubilees 2:2), angels who pray on behalf of humans (1 Enoch 39:5; 47:2; Revelation 8:3-4), recording angels who keep a record of sins (1 Enoch 89: 61-4; Testament of Abraham 12:12), angels who administer eschatological punishment (1 Enoch 53:4-5; 55:3; 56:1-4; 62:11; 63:1; 2 Enoch 10:3; Testament of Levi 3:2; Testament of Abraham 12:1-2), personal guardian angels (Jubilees 35:17; Daniel 3:6; 3 Baruch 12-13) and guardian angels of the nations (Daniel 10:13, 21; 12:1; 1 Enoch 89:59-62; Jubilees 15:31-2). At the very top of this hierarchy and closest to God are the archangels, four in number according to some traditions (1 Enoch 40:2-9; 54:6; 71:8) or seven in number according to others (1 Enoch 20:1-7; 81:5; 90:21-2). This class of angel has a variety of functions, including the imprisonment of the fallen angels (1 Enoch 10:4-5) and the consignment of them into the fiery furnace on the day of judgement (1 Enoch 54:6). Normally it is one of these who takes the purported author of the apocalypse through the heavenly regions and explains the heavenly secrets ..."
