Ps 68:17 The chariots of God are tens of thousands and thousands of thousands; the Lord has come from Sinai into his sanctuary.NIV
Gill's Exposition of the Entire Bible Ps 68:17
The chariots of God are twenty thousand,.... By which are meant the angels, as the following clause shows; called "chariots", because they have appeared in such a form,2 Kings 2:11; and because, like chariots of war, they are the strength and protection of the Lord's people; and because of their swiftness in doing his work; and because they are for his honour and glory: they are the chariots of God, in which he rides about the world doing his will; they are the chariots in which Christ ascended up to heaven, and in which he will descend at the last day; and in which he now fetches the souls of his people to him at death, and will make use of them at the resurrection to gather them to him, when their bodies are raised by him: their number is very great, and in other places is mentioned as greater,Daniel 7:10; Christ speaks of twelve legions of them, Matthew 26:53; there is a multitude of them, and they are said to be even innumerable,Luke 2:13; which is observed, both for the glory of God, and for the safety of his people:
Deuteronomy 33:2 He said: "The LORD came from Sinai and dawned over them from Seir; he shone forth from Mount Paran. He came with myriads of holy ones from the south, from his mountain slopes.
2 Kings 6:17 And Elisha prayed, "O LORD, open his eyes so he may see." Then the LORD opened the servant's eyes, and he looked and saw the hills full of horses and chariots of fire all around Elisha.
Notes on v. 17. Elisha prayed, and said, Lord, I pray thee, open his eyes, that he may see—The invisible guard of angels that encompass and defend us (Ps 34:7). The opening of the eyes, which Elisha prayed for, were those of the Spirit, not of the body—the eye of faith sees the reality of the divine presence and protection where all is vacancy or darkness to the ordinary eye. The horses and chariots were symbols of the divine power (see on 2Ki 2:12); and their fiery nature denoted their supernatural origin; for fire, the most ethereal of earthly elements, is the most appropriate symbol of the Godhead [Keil].

Daniel 7:10 A river of fire was flowing, coming out from before him. Thousands upon thousands attended him; ten thousand times ten thousand stood before him. The court was seated, and the books were opened.
Barnes' Notes on the Bible on Daniel 7:10
A fiery stream issued and came forth from before him - Streams of fire seemed to burst forth from his throne. Representations of this kind abound in the Scriptures to illustrate the majesty and glory of God. Compare Revelation 4:5, "And out of the throne proceeded lightnings, and thunderings, and voices."Exodus 19:16; Habakkuk 3:4;Psalm 18:8.
Thousand thousands ministered unto him - "A thousand of thousands;" that is, thousands multiplied a thousand times. The mind is struck with the fact that there are thousands present - and then the number seems as great as if those thousands were multiplied a thousand times. The idea is that there was an immense - a countless host. The reference here is to the angels, and God is often represented as attended with great numbers of these celestial beings when he comes down to our world.Deuteronomy 33:2, "he came with ten thousands of saints;" that is, of holy ones. Psalm 68:17, "the chariots of God are twenty thousand, even thousands of angels." Compare Jde 1:14. The word "ministered" means that they attended on him.
And ten thousand times ten thousand stood before him - An innumerable host
1. The LORD is accompanied by Legions of angels. He is a Mighty Conqueror and He is powerful.
2. The Lord can open the eyes of our understanding till we see and realise that more are they who are for us than they who are against us. Greater is He who is in us than he who is in the world.
