Revelation 20:2

“that old--ancient serpent (Rev 12:9). thousand years--As seven mystically implies universality, so a thousand implies perfection, whether in good or evil [AQUINAS on ch. 11]. Thousand symbolizes that the world is perfectly leavened and pervaded by the divine; since thousand is ten, the number of the world, raised to the third power, three being the number of God [AUBERLEN]. It may denote literally also a thousand years.”

“And he laid hold on - Seized him by violence - ἐκράτησεν ekratēsen. The word denotes “the employment of strength” or “force”; and it implies that he had power superior to that of the dragon. Compare Matthew 14:3; Matthew 18:28; Matthew 21:46; Matthew 22:6; Matthew 26:4. We can at once see the propriety of the use of this word in this connection. The great enemy to be bound has himself mighty power, and can be overcome only by a superior. This may teach us that it is only a power from heaven that can destroy the empire of Satan in the world; and perhaps it may teach us that the interposition of angels will be employed in bringing in the glorious state of the millennium. Why should it not…”

“And he laid hold on the dragon - With whom undoubtedly his angels were now cast into the bottomless pit, as well as finally "into everlasting fire," Mat 25:41. And bound him a thousand years - That these thousand do not precede, or run parallel with, but wholly follow, the times of the beast, may manifestly appear, 1. From the series of the whole book, representing one continued chain of events. 2. From the circumstances which precede. The woman's bringing forth is followed by the casting of the dragon out of heaven to the earth. With this is connected the third woe, whereby the dragon through, and with, the beast, rages horribly. At the conclusion of the third woe the beast is overthrown…”
