Bamidbar 3:2-4

Orthodox Jewish Bible

² And these are the shmot of the Bnei Aharon: Nadav the bechor, and Avihu, Eleazar, and Itamar [Vayikra 10].

³ These are the shmot of the Bnei Aharon, the kohanim hameshuchim whose hand he filled [i.e., ordained] to be kohen [Shemot 29; Vayikra 8].

⁴ And Nadav and Avihu died before Hashem, when they offered eish zarah (unauthorized fire) before Hashem, in the midbar of Sinai, and they had no children; and Eleazar and Itamar ministered in the kohen’s office in the sight of Aharon their av [Vayikra 10].
