Rev 5:9
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; And hast made us unto our God kings and priests: and we shall reign on the earth.
That does not say they will reign for the 1000 years on earth.... read it .... AND,
AND we shall reign on the earth.
I will not make it say something it isn't...
But when you read the other bible verses in Revelation it is clear that the holy city does not come down until the end of the 1000 years. And Jesus said He is preparing mansions in heaven.
And the devil is chained up for the 1000 years.
And, The slain of the Lord shall be from one end of the earth even to the other end of the earth. They shall not be lamented, or gathered, or buried; they shall become refuse on the ground (Jeremiah 25:33).
I beheld, and indeed there was no man (Jeremiah 4:25).
It will be impossible for any person to repent during the 1,000 years because there will not be a person alive on the earth. The righteous will all be in heaven. All the wicked will be laying dead upon the earth. Revelation 22:11, 12 makes it clear that the case of every person is closed before Jesus returns. Those who wait to accept Christ until the 1,000 years begin will have waited too long.
I saw an angel coming down from heaven, having the key to the bottomless pit. …
He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; and he cast him into the bottomless pit … till the thousand years were finished (Revelation 20:1–3).
The word for bottomless pit in the original Greek is abussos, or abyss. That same word is used in Genesis 1:2 in the Greek version of the Old Testament in connection with the creation of the earth, but there it is translated deep. The earth was without form, and void; and darkness was on the face of the deep. The words deep, bottomless pit, and abyss here refer to the same thing the earth in its totally dark, disorganized form before God made order of it. Jeremiah, in describing this earth during the 1,000 years, used virtually the same terms as these in Genesis 1:2: without form, and void, no light, no man, and black (Jeremiah 4:23, 25, 28). So the battered, dark earth with no people alive will be called the bottomless pit, or abyss, during the 1,000 years, just as it was in the beginning before Creation was completed. Also, Isaiah 24:22 speaks of Satan and his angels during the 1,000 years as gathered in the pit and shut up in the prison.
Isa 24:22 And they shall be gathered together,
as prisoners are gathered in the pit, and shall be shut up in the prison, and after many days shall they be visited.

An angel … having … a great chain in his hand … laid hold of … Satan, and bound him for a thousand years … and shut him up, and set a seal on him, so that he should deceive the nations no more till the thousand years were finished (Revelation 20:1–3).
The chain is symbolic. A chain of circumstances. A super-natural being cannot be confined with a literal chain. Satan is tied down because he has no people to deceive. The unsaved are all dead and the saved are all in heaven. The Lord confines the devil to this earth so he cannot roam the universe hoping to find someone to deceive. Forcing the devil to stay on the earth, alone with his demons for a thousand years with no one to deceive, will be for him the most galling chain ever forged.
At the end of the 1000 years Satan is loosed for a short time because the wicked are raised for the second death, But this is when Jesus will make all things new and death is fully destroyed.
Joh 13:36 Simon Peter said unto him, Lord, whither goest thou? Jesus answered him, Whither I go, thou canst not follow me now; but thou shalt follow me afterwards.
