“And when the thousand years are expired, Satan shall be loosed out of his prison,”
King James Version (KJV)
20:7 And when the former thousand years are fulfilled, Satan shall be loosed out of his prison - At the same time that the first resurrection begins. There is a great resemblance between this passage and #Rev 12:12|. At the casting out of the dragon, there was joy in heaven, but there was woe upon earth: so at the loosing of Satan, the saints begin to reign with Christ; but the nations on earth are deceived.
Re 20:7 And when the thousand years are expired, Satan shall be loosed. The earth shall have its golden age, but it shall not last forever. Satan shall, when many aged have rolled away, be loosed for a little season. From some cause that is wrapped in the darkness of the future, righteousness shall wane; wickedness shall revive; the great adversary shall in part regain his influence over our race. But it is cheering to know that his triumph will be short. He shall be loosed only "for a little season" (Re 20:3).
