and I heard the voice of many angels round about the throne and the beasts and the elders; and I heard many angels, with the living creatures and the elders; (from whence we gather, that we must not, by the living creatures, or elders, understand angels, for they are mentioned apart by themselves, neither could they say, as Rev_5:9,10, that Christ had redeemed them with his blood); these angels joined in this harmony with the church to give glory to Christ.
And the number of them was ten thousand times ten thousand, and thousands of thousands; their number was infinite, not to be numbered. See the like, Dan_7:10.
