3:11 And the LORD spake unto Moses, saying,
3:12 And I, behold, I have taken the Levites from among the children of Israel instead of all the firstborn that openeth the matrix among the children of Israel: therefore the Levites shall be mine;
3:13 Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the LORD.
3:14 And the LORD spake unto Moses in the wilderness of Sinai, saying,
3:15 Number the children of Levi after the house of their fathers, by their families: every male from a month old and upward shalt thou number them.
3:16 And Moses numbered them according to the word of the LORD, as he was commanded.
3:17 And these were the sons of Levi by their names; Gershon, and Kohath, and Merari.
3:18 And these are the names of the sons of Gershon by their families; Libni, and Shimei.
3:19 And the sons of Kohath by their families; Amram, and Izehar, Hebron, and Uzziel.
