2. Satan cast into the abyss. “ And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season."--20:3.
In the vision Satan returned from his prowling to his diabolical abode in ignominious and complete defeat. His abysmal abode was shut by the angel with the key to the bottomless pit that he held; which angel also set a seal upon him, as an authoritative act; such as the seal of state stamped on the documents signed by officials of government.
The purpose of this satanic imprisonment was that he should deceive the nations no more--that is, in the idolatry of Caesar-worship, a repetition of the previous symbols of the mark and image of the beast in the heathen emperorworship.
The next clause till the thousand years be fulfilled referred to the complete victory over the imperial persecutors, after which Satan was represented as being unleashed to exert influence, not in the form of persecution, but in the spiritual conflict between heathenism and Christianity--a symbolic representation of the upsurge of heathenism.
