What is the Bible's
definition of a Generation:
40 years: (Numbers 32:11-13) Jehovah's anger blazed against Israel and he made them wander in the
wilderness for 40 years, until all the generation that was doing evil in the
eyes of Jehovah came to its end.
35 years: (Job 42:16, 17) "And Job continued living after this a hundred and forty years and came to
see his sons and his grandsons—four generations.
37 years:
Jerusalem was destroyed about 37 years later when Jesus said "this
generation will by no means pass away"
38 years:
Deut 2:14 - And the days that we walked from Ka'desh-bar'ne·a
until we crossed the torrent valley of Ze'red were thirty-eight years, until
all the generation of the men of war had come to their end.
(Mt 1:17) "All the
generations, then, from Abraham until David were fourteen generations, and from
David until the deportation to Babylon fourteen generations, and from the
deportation to Babylon until the Christ fourteen generations". When you
read the list in Matthew, none of them are described as overlapping:
65 years - Abraham to David
: 2018BCE -> 1107BCE / 14 generations = 65 years
35 years - David to
deportation : 1107BCE -> 607BCE / 14 generations = 35 years
45 years - Deportation to
Christ : 607BCE -> 29CE / 14 generations = 45 years
