Numbers 3:2-4 Tree of Life Version (TLV)
2 These are the names of Aaron’s sons: Nadab the first-born, Abihu, Eleazar and Ithamar. 3 These are the names of the sons of Aaron, the anointed kohanim whom he consecrated to be priests. 4 But Nadab and Abihu died before Adonai for offering unauthorized fire[a] before Adonai in the Sinai wilderness—they had no children. So Eleazar and Ithamar served as kohanim under Aaron their father.
