So you did not read about those that praised the one who took the scroll for redeeming them from their sin, who laid their crowns at his feet?
Who are these people?
They are not people. They were original to heaven. The tabernacle was the pattern on earth to show what existed in heaven.
Hebrews 8:5 "Who serve unto
the example and shadow of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou
make all things according to the pattern shewed to thee in the mount."
There were 24 men on earth to duplicate heaven as shown in 1 Chronicles 24:
24 Now these are the divisions of the sons of Aaron. The sons of Aaron; Nadab, and Abihu, Eleazar, and Ithamar.
2 But Nadab and Abihu died before their father, and had no children: therefore Eleazar and Ithamar executed the priest's office.
3 And David distributed them, both Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, according to their offices in their service.
4 And there were more chief men found of the sons of Eleazar than of the sons of Ithamar, and thus were they divided. Among the sons of Eleazar there were
sixteen chief men of the house of their fathers,
and eight among the sons of Ithamar according to the house of their fathers.
Rev 4:
10 The four and twenty elders fall down before him that sat on the throne, and worship him that liveth for ever and ever, and cast their crowns before the throne, saying,
11 Thou art worthy, O Lord, to receive glory and honour and power: for thou hast created all things, and for thy pleasure they are and were created.
In Rev 4, people knew God because of creation. Verse 11 is the original song in heaven.
In Rev 5, people knew God because of Jesus.
8 And when he had taken the book, the four beasts and four and twenty elders fell down before the Lamb, having every one of them harps, and golden vials full of odours, which are the prayers of saints.
9 And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation;
10 And hast made us unto our God kings and priests: and we shall reign on the earth.
The new song in verse 9 is sung in heaven from the moment Jesus arrived in heaven as the sacrifice for sin, the slain lamb. This had to be done in heaven to prepare heaven for mankind. Man could not enter heaven until this time.
John 14:
2 In my Father's house are many mansions: if it were not so, I would have told you.
I go to prepare a place for you.
3 And if I go and prepare a place for you, I will come again, and receive you unto myself;
that where I am, there ye may be also.
Hebrews 10:12 "12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God"
Jesus just entered heaven in Rev 5. He had not yet sat down on the right hand of God. Until Jesus went to heaven as the slain lamb, heaven was not prepared for mankind. Mankind was still at this point separated from God because of sin.
