11 And Jehovah spoke to Moses, saying,
12 And I, behold, I have taken the Levites from among the children of Israel instead of every firstborn that breaketh open the womb among the children of Israel, and the Levites shall be mine;
13 for every firstborn is mine. On the day that I smote all the firstborn in the land of Egypt, I hallowed unto me all the firstborn in Israel, both of man and beast; mine shall they be: I am Jehovah.
14 And Jehovah spoke to Moses in the wilderness of Sinai, saying,
15 Number the sons of Levi according to their fathers' houses, after their families; every male from a month old and upward shalt thou number them.
16 And Moses numbered them, according to the commandment of Jehovah, --as he had been commanded.
17 And these are the sons of Levi by their names: Gershon, and Kohath, and Merari.
