Shemot
A Census of Israel's Familys with an approximate growth rate average of 5.44 males per generation (excluding Levi) from the time of Jacob's arrival with a total number of seventy. The average family would have to have had approximately 5.44 males, per generation, to achieve a total 60,355 (603,550 or 54 males/ family would not be achievable). However, the example familys given are: Joseph - two sons; Levi's family - three males; Kohath - four sons; Amram's family there were two boys - Aaron and Moses. Joseph's, Levi's, Kohath's and Amram's families were all below the average. Someone must have added a zero to the numbers along the way.
And these are the names of the sons of Levi according to their generations; Gershon, and Kohath, and Merari: and the years of the life of Levi were an hundred thirty and seven years. And the sons of Kohath; Amram, and Izhar, and Hebron, and Uzziel: and the years of the life of Kohath were an hundred thirty and three years. And the sons of Merari; Mahali and Mushi: these are the families of Levi according to their generations. And Amram took him Yocheved (Jochebed) his father's sister to wife; and she bare him Aaron and Moses: and the years of the life of Amram were an hundred and thirty and seven years.
