11. And the Lord said to Moses,
12. Behold, I have taken the Levites from among the Israelites instead of every firstborn who opens the womb among the Israelites; and the Levites shall be Mine,
13. For all the firstborn are Mine. On the day that I slew all the firstborn in the land of Egypt, I consecrated for Myself all the firstborn in Israel, both man and beast; Mine they shall be. I am the Lord.
14. And the Lord said to Moses in the Wilderness of Sinai,
15. Number the sons of Levi by their fathers' houses and by families. Every male from a month old and upward you shall number.
16. So Moses numbered them as he was commanded by the word of the Lord.
17. These were the sons of Levi by their names: Gershon, Kohath, and Merari.
18. And these are the names of the sons of Gershon by their families: Libni and Shimei.
19. The sons of Kohath by their families: Amram, Izhar, Hebron, and Uzziel.
20. The sons of Merari by their families: Mahli and Mushi. These are the families of the Levites by their fathers' houses.
21. Of Gershon were the families of the Libnites and of the Shimeites. These are the families of the Gershonites.
22. The males who were numbered of them from a month old and upward totaled 7,500.
23. The families of the Gershonites were to encamp behind the tabernacle on the west,
24. The leader of the fathers' houses of the Gershonites being Eliasaph son of Lael.
