How old is the oldest person in the Bible?
That is an easy one.
Enoch is the oldest person of all time, and the second oldest is Elijah. Both were taken to heaven directly from earth without dying (Gen. 5:21-24; 2 Kings 2:11). They are still alive, waiting to come back as the two witnesses described in Revelation who will testify for about 3 1/2 years (1260 days) against the anti-Christ in the last half of the tribulation. They will eventually be killed, fulfilling Heb. 9:27, and then resurrected three and one half days later (Rev. 11:3-13).
