~ This 1,000 year period begins about 6000 (6,000) years after creation, and ends about 7000 (7,000) years after creation.  Hence this 7th 1,000 years since creation, the 7th millennium, is the millennium of "rest" (God rested on the 7th day of creation week).

~ Note: The 8th 1,000 years since creation, begins eternity with the New Jerusalem.

Rev 20:1  And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.

Rev 20:2  And he laid hold on the dragon, that old serpent, which is the Devil, and Satan [the 4 "names" of Satan ], and bound him [Satan] a thousand [ 1000  1,000 ] years,

Rev 20:3  And cast him [Satan] into the bottomless pit, and shut him up, and set a seal upon him,   ^   that he [Satan] should deceive the nations no more, till the thousand [ 1000  1,000 ] years should be fulfilled:   ^   and after that he [Satan] must be loosed a little season.   ^ 
 

Rev 20:5  But the rest of the dead lived not again until the thousand [ 1000  1,000 ] years were finished.   ^   This is the first resurrection.   ^     

Rev 20:7  And when the thousand [ 1000  1,000 ] years are expired, Satan shall be loosed out of his prison,   ^ 

Rev 20:8  And shall go out to deceive the nations which are in the four [ 4 ] quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea.   ^ 

Rev 20:9  And they went up on the breadth of the earth, and compassed [surrounded] the camp of the saints about, and the beloved city [Jerusalem?]:   ^   and fire came down from God out of heaven, and devoured them.   ^ 

Rev 20:10  And the devil [Satan] that deceived them was cast into the lake of fire and brimstone, where the [sea] beast [the antichrist [ac]] and the false prophet [the earth beast [fp]] are, and shall be tormented day and night for ever and ever.  [ The final demise of Satan's "trinity" ]   ^
