“Now the sons of Jacob were twelve: the sons of Leah; Reuben, Jacob’s firstborn, and Simeon, and Levi,” etc. (Gen. xxxv, 22, 23).
“And these are the names of the sons of Levi, according to their generations: Gershon, and Kohath” etc. (Ex. vi, 16).
“And the sons of Kohath; Amram,” etc. (18).
“And Amram took him Jochebed his father’s sister to wife; and she bare him Aaron and Moses” (20).
“And the children of Israel journeyed from Ramases to Succoth, about six hundred thousand on foot that were men, beside children” (Ex. xii, 37.
Levi was the son of Jacob, Kohath was the son of Levi, Amram was the son of Kohath, and Moses was the son of Amram. Moses was the fourth generation from Jacob. In the time of Moses the adult male population of Israel numbered 600,000, representing a total population of about 3,000,000. Thus in four generations the progeny of Jacob increased from twelve persons to three millions.
