2. Aaron's four sons, Nadab, Abihu, Eleazar, and Ithamar,
3. were the ones to be ordained as priests.
4. But the Lord killed Nadab and Abihu in the Sinai Desert when they used fire that was unacceptable in their offering to the Lord. And because Nadab and Abihu had no sons, only Eleazar and Ithamar served as priests with their father Aaron.
5. The Lord said to Moses:
6. Assign the Levi tribe to Aaron the priest. They will be his assistants
36-37. Their duties included taking care of the tent frames and the pieces that held the tent up: the bars, the posts, the stands, and its other equipment. They were also in charge of the posts that supported the courtyard, as well as their stands, tent pegs, and ropes. The Merari clans were responsible for setting these things up and taking them down.
