2 And He seizes (or: put a power-hold on) the dragon, the primeval (ancient; original) serpent, who is a false accuser and the adversary (or: a devil, even satan), and He binds (or: bound) it (or: him) "a thousand years."
3 Then He casts (or: threw) it (or: him) into the Deep (or: abyss) and He closes (or: shut; locked) and seals (or: stamped with a seal) over upon it (or: him), to the end that it (or: he) can no longer (or: would not still) deceive (lead astray; cause to wander) the multitudes (the nations; the non-Israelites; the ethnic groups), until the thousand years may be ended (finished, completed, perfected; brought to the destined goal; can have its purpose fulfilled). After these [events; things], it is necessary for it to be loosed [for] a little time.
