Length of A Generation

A generation is defined as a length of time it takes for a father to be succeeded by his child. It is popularly considered to be 33 years.

A Bible generation is sometimes regarded as 70 years (Psalm 90:10). Others believe it to be 40 years, saying that all the adults of the generation which left Egypt died during the 40-year wilderness wanderings.

Perhaps the strongest identification is found in Job 42:16 which says that “Job lived a hundred and forty years . . . even four generations.” Dividing 140 by 4, the result is 35. A Bible generation could very well be 35 years.
