Daniel 7:10
8 “As I was contemplating the horns, another horn—a small one—came up between them, and three of the former horns were torn out by the roots to make room for it. This horn had eyes resembling human eyes and a mouth speaking arrogant things. 9 “While I was watching, thrones were set up, and the Ancient of Days took his seat. His attire was white like snow; the hair of his head was like lamb’s wool. His throne was ablaze with fire, and its wheels were all aflame. 10 A river of fire was streaming forth and proceeding from his presence. Many thousands were ministering to him; many tens of thousands stood ready to serve him. The court convened, and the books were opened. 11 “Then I kept on watching because of the arrogant words of the horn that was speaking. I was watching until the beast was killed and its body destroyed and thrown into the flaming fire.
Revelation 5:11
7 Then he came and took the scroll from the right hand of the one who was seated on the throne, 8 and when he had taken the scroll, the four living creatures and the twenty-four elders threw themselves to the ground before the Lamb. Each of them had a harp and golden bowls full of incense (which are the prayers of the saints). 9 They were singing a new song: “You are worthy to take the scroll and to open its seals because you were killed, and at the cost of your own blood you have purchased for God persons from every tribe, language, people, and nation. 10 You have appointed them as a kingdom and priests to serve our God, and they will reign on the earth.” 11 Then I looked and heard the voice of many angels in a circle around the throne, as well as the living creatures and the elders. Their number was ten thousand times ten thousand—thousands times thousands— 12 all of whom were singing in a loud voice: “Worthy is the lamb who was killed to receive power and wealth and wisdom and might and honor and glory and praise!”
Notes and References
"... Though in reverse order, the presence of “myriads of myriads” and “thousands of thousands” is shared by two passages in the Book of Parables (40:1; 71:8; for the same order see Apoc. Zeph. 4:1; 8:1; 1 Clem. 34:6) with Revelation 5:11, whereas Psalm 68:17 refers to “a myriad thousands,” and the Book of Giants, in a tradition that relates to Daniel 7, describes the worship of God by “thousands” and “hundreds.” The sequence in Revelation, however, corresponds to that of the Book of Watchers (1 Enoch 14:22) and to Daniel 7:10, either text of which is likely to have shaped the wording here ..."
