God then spoke about Aaron’s family and the Levites. Aaron’s sons were Nadab, Abihu, Eleazar, and Ithamar. Nadab and Abihu died in the wilderness when they brought “alien fire” before God, so Eleazar and Ithamar served as priests with Aaron.
The Levites were set apart to assist Aaron and to care for the Tent of Meeting and its furnishings. They were counted separately, every male from one month old and up, and the total was 22,000. Their clans were Gershon, Kohath, and Merari, each with assigned work and a place to camp: Gershon to the west, Kohath to the south, Merari to the north, while Moses, Aaron, and the priests camped on the east.
God said the Levites would be taken in place of Israel’s first-born males. When Moses counted the first-born, there were 22,273, 273 more than the Levites, so a redemption payment of five shekels each was given to Aaron and his sons.
Finally, God gave careful rules for moving the most sacred objects. Aaron and his sons had to cover the Ark, the table, the lampstand, and the altars before the Kohathites could lift them, so no one would touch the holy items and die.
