'End of the Age' in the Bible

And the whole valley (Hinnom) of the dead bodies and [the hill] of the ashes [long dumped there from the temple sacrifices], and all the fields as far as the brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to the Lord. It (the city) will not be uprooted or overthrown anymore to the end of the age.”

Now as for you, keep on going until the end you'll rest and then rise to receive your reward at the end of the age.'"
