1This is the list of Aaron and Moses’ descendants when Jehovah spoke to Moses on Mount Sinai. 2The names of Aaron’s sons are Nadab firstborn, Abihu, Eleazar, and Ithamar. 3These are the names of Aaron’s sons, the anointed priests, who were ordained to serve as priests. 4Nadab and Abihu died in Jehovah’s presence because they offered unauthorized fire in his presence in the Desert of Sinai. They had no children. So only Eleazar and Ithamar served as priests during the lifetime of their father Aaron. 5Jehovah said to Moses: 6»Bring the tribe of Levi, and have them stand in front of the priest Aaron to assist him. 7»They will work for him and the whole community in front of the tent of meeting, doing what needs to be done for the inner tent. 8»They will take care of all the furnishings in the tent of meeting and work for the Israelites, doing what needs to be done for the inner tent. 9»Give the Levites to Aaron and his sons. The Levites will be the only Israelites given to them. 10»Appoint Aaron and his sons to serve as priests. Anyone else who tries to do the priests’ duties must be put to death.« 11Jehovah said to Moses: 12»Out of all the Israelites, I have taken the Levites to be substitutes for every firstborn male offspring among them. The Levites are mine, 13because every firstborn is mine. The day I killed every firstborn male in Egypt, I set apart as holy every firstborn in Israel, whether human or animal. They will be mine. I am Jehovah.« 14Jehovah said to Moses in the Desert of Sinai: 15»Count the Levites by households and families. Count every male who is at least one month old.« 16Moses did what Jehovah said. He registered them as he had been commanded. 17Gershon, Kohath, and Merari were the sons of Levi. 18Libni and Shimei were the sons of Gershon. Their families were named after them. 19Amram, Izhar, Hebron, and Uzziel were the sons of Kohath. Their families were named after them. 20Mahli and Mushi were the sons of Merari. Their families were named after them. These were the households of Levite families. 21To Gershon belonged the families descended from Libni and Shimei. These were the families descended from Gershon. 22The total number of all the males at least one month old was seven thousand five hundred. 23The families descended from Gershon put up their tents on the west side behind the tent of meeting. 24The leader of the Gershonite households was Eliasaph, son of Lael. 25The Gershonites were in charge of the inner tent, the outer tent and cover, the screen for the entrance to the tent of meeting, 26the curtains for the courtyard, the screen for the entrance to the courtyard that surrounds the inner tent and the altar, and the ropes. They took care of all these things. 27To Kohath belonged the families descended from Amram, Izhar, Hebron, and Uzziel. These were the families descended from Kohath. 28The number of all the males at least one month old was eight thousand six hundred. They were in charge of the holy place. 29The families descended from Kohath put up their tents on the south side of the tent of meeting. 30The leader of the Kohathite families and households was Elizaphan, son of Uzziel. 31They were in charge of the Ark, the table, the lamp stand, the altars, the utensils used in the holy place, and the screen. They took care of all these things. 32The leader of the Levites was Eleazar son of Aaron the priest. He was in charge of those who carried out the duties in the Holy Place. 33The clan of Merari was composed of the families of Mahli and Mushi. 34The total number of males one month old or older that were enrolled was six thousand two hundred. 35This clan was to camp on the north side of the Tent, with Zuriel son of Abihail as leader of the clan. 36It was the duty of the Merarites to be in charge of the framework of the inner tent, the crossbars, posts, sockets, and all the equipment. They took care of these things. 37They were responsible for the posts for the surrounding courtyard, the bases, pegs, and ropes. 38Moses, Aaron, and his sons put up their tents on the east side in front of the tent of meeting. They were in charge of the holy place on behalf of the Israelites. Anyone else who tried to do the Levites’ duties had to be put to death. 39The grand total of Levites that Moses and Aaron counted at Jehovah’s command, by families, every male who was at least one month old, was twenty-two thousand. 40Jehovah said to Moses: »Register every firstborn male of the Israelites who is at least one month old, and make a list of their names. 41»I am Jehovah. Take the Levites for me to be substitutes for all firstborn Israelites. Also take the animals of the Levites to be substitutes for all firstborn animals of the Israelites.« 42Moses registered all the firstborn Israelites as Jehovah commanded him. 43The total of all the firstborn males at least one month old was twenty-two thousand two hundred and seventy three. They were listed by name. 44Jehovah said to Moses: 45»Take the Levites to be substitutes for all the firstborn Israelites and the animals of the Levites to be substitutes for their animals. The Levites will be mine. I am Jehovah. 46»There are two hundred and seventy-three more firstborn male Israelites than there are Levites. 47»It will cost you two ounces of silver per person, using the standard weight of the holy place, to buy them back. 48»Give the silver to Aaron and his sons. It will buy back those Israelites who outnumber the Levites.« 49Moses took this ransom money from the Israelites who outnumbered the Levites. 50The silver Moses collected for the firstborn Israelites weighed thirty-four pounds using the standard weight of the holy place. 51Then Moses did what Jehovah said and gave Aaron and his sons this ransom money as he had been commanded.
