Numbers 3:5

3 These were Aaron’s sons, the anointed priests, who were ordained to serve as priests.

4 Nadab and Abihu, however, died in the presence of the LORD when they offered unauthorized fire before the LORD in the Wilderness of Sinai. And since they had no sons, only Eleazar and Ithamar served as priests during the lifetime of their father Aaron.

Then the LORD said to Moses,

6 “Bring the tribe of Levi and present them to Aaron the priest to assist him.

7 They are to perform duties for him and for the whole congregation before the Tent of Meeting, attending to the service of the tabernacle.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
