'Seal Up' in the Bible

'Seventy weeks are determined for thy people, and for thy holy city, to shut up the transgression, and to seal up sins, and to cover iniquity, and to bring in righteousness age-during, and to seal up vision and prophet, and to anoint the holy of holies.

and he cast him to the abyss, and did shut him up, and put a seal upon him, that he may not lead astray the nations any more, till the thousand years may be finished; and after these it behoveth him to be loosed a little time.
