'Ages' in the Bible

But the saints of the most high places shall receive the kingdom, and they shall possess the kingdom for ever, even to the ages of ages.

Seventy weeks are apportioned out upon thy people and upon thy holy city, to close the transgression, and to make an end of sins, and to make expiation for iniquity, and to bring in the righteousness of the ages, and to seal the vision and prophet, and to anoint the holy of holies.
