Jehovah`s Witnesses make a big deal about the 2 or 3 witnesses in judicial decisions yet they ignore that evidence when it suits them.
Firstly :
Regarding the length of a generation matthew ch.1:17 gives a strong clue ,their are 3 lots of 14 generations mentioned which equal 42 generations from the time of Abraham to Jesus .
Watchtower publications give Abrahams birth as 2018 BC......They also give jesus birth as of 2 BC a period of 2016 years
2016 yrs. divided by 42 gen. =48 years per generation
Secondly:
Luke Ch.3 : 23 - 38 indicates their are 76 generations from Adams creation to the birth of Jesus a period of 4024 years according to watchtower chronology .
4024 years divided by 76 generations =53 years per generation
Warning : Dont be misled by a furphy , how long a person or group lives has nothing to do with how long a generation is .
Thirdly:
When Jesus gave his prophecy in Matt.24 :34 "this generation will by no means pass away untill all these things occur." he was no older than 33 years right ? This prophecy occured in the year 70 AD., well within the 50 year timeslot for a generation as outlined in Gods word the Bible .
Conclusion : Gods word the bible testifies 3 times that a generation is no longer than 50 + or - a couple of years
Nowwhere in either the Hebrew scriptures or Christian greek scriptures is their any justification for proclaiming an extension of this time period for a generation.
