G5055–τελέω–teleō

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.

τελεσθῇ telesthēa “may be completed”

But the rest of the dead lived not again until the thousand years were finished. This is the first resurrection.

τελεσθῇ telesthēa “may have been completed”

And when the thousand years are expired, Satan shall be loosed out of his prison,

τελεσθῇ telesthēa “may have been completed”
