Numbers 3, Levites Dedicated to God, Tabernacle, Redemption Price for Firstborn

Numbers 3
1 Now these are the records of Aaron and Moses when the Lord spoke with Moses on Mount Sinai.
2 And these are the names of the sons of Aaron: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.
3 These are the names of the sons of Aaron, the anointed priests, whom he consecrated to minister as priests.
4 Nadab and Abihu had died before the Lord when they offered profane fire before the Lord in the Wilderness of Sinai; and they had no children. So Eleazar and Ithamar ministered as priests in the presence of Aaron their father.
5 And the Lord spoke to Moses, saying:
6 "Bring the tribe of Levi near, and present them before Aaron the priest, that they may serve him.
7 And they shall attend to his needs and the needs of the whole congregation before the tabernacle of meeting, to do the work of the tabernacle.
8 Also they shall attend to all the furnishings of the tabernacle of meeting, and to the needs of the children of Israel, to do the work of the tabernacle.
9 And you shall give the Levites to Aaron and his sons; they are given entirely to him from among the children of Israel.
10 So you shall appoint Aaron and his sons, and they shall attend to their priesthood; but the outsider who comes near shall be put to death."
11 Then the Lord spoke to Moses, saying:
12 "Now behold, I Myself have taken the Levites from among the children of Israel instead of every firstborn who opens the womb among the children of Israel. Therefore the Levites shall be Mine,
13 because all the firstborn are Mine. On the day that I struck all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, both man and beast. They shall be Mine: I am the Lord."
14 Then the Lord spoke to Moses in the Wilderness of Sinai, saying:
15 "Number the children of Levi by their fathers' houses, by their families; you shall number every male from a month old and above."
16 So Moses numbered them according to the word of the Lord, as he was commanded.
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 And the sons of Kohath by their families: Amram, Izehar, Hebron, and Uzziel.
20 And the sons of Merari by their families: Mahli and Mushi. These are the families of the Levites by their fathers' houses.
21 From Gershon came the family of the Libnites and the family of the Shimites; these were the families of the Gershonites.
22 Those who were numbered, according to the number of all the males from a month old and above--of those who were numbered there were seven thousand five hundred.
23 The families of the Gershonites were to camp behind the tabernacle westward.
24 And the leader of the fathers' house of the Gershonites was Eliasaph the son of Lael.
25 The duties of the children of Gershon in the tabernacle of meeting included the tabernacle, the tent with its covering, the screen for the door of the tabernacle of meeting,
26 the screen for the door of the court, the hangings of the court which are around the tabernacle and the altar, and their cords, according to all the work relating to them.
27 From Kohath came the family of the Amramites, the family of the Izharites, the family of the Hebronites, and the family of the Uzzielites; these were the families of the Kohathites.
28 According to the number of all the males, from a month old and above, there were eight thousand six hundred keeping charge of the sanctuary.
29 The families of the children of Kohath were to camp on the south side of the tabernacle.
30 And the leader of the fathers' house of the families of the Kohathites was Elizaphan the son of Uzziel.
31 Their duty included the ark, the table, the lampstand, the altars, the utensils of the sanctuary with which they ministered, the screen, and all the work relating to them.
32 And Eleazar the son of Aaron the priest was to be chief over the leaders of the Levites, with oversight of those who kept charge of the sanctuary.
33 From Merari came the family of the Mahlites and the family of the Mushites; these were the families of Merari.
34 And those who were numbered, according to the number of all the males from a month old and above, were six thousand two hundred.
35 The leader of the fathers' house of the families of Merari was Zuriel the son of Abihail. These were to camp on the north side of the tabernacle.
