1 Chronicles 24:2

But Nadab and Abihu died before their father
While he was living, see ( Leviticus 10:1 Leviticus 10:2 )

and had no children, therefore Eleazar and Ithamar executed the
priests' office:
otherwise, as Jarchi observes, had their brethren left children, they would have come into the office before them.

1 Chronicles 24:2 In-Context

1 Now the divisions into which the sons of Aaron were grouped were these: the sons of Aaron, Nadab and Abihu, Eleazar and Ithamar.

2 But Nadab and Abihu came to their end before their father, and had no children; so Eleazar and Ithamar did the work of priests.

3 And David, with Zadok of the sons of Eleazar, and Ahimelech of the sons of Ithamar, made distribution of them into their positions for their work.

4 And there were more chiefs among the sons of Eleazar than among the sons of Ithamar; and this is how they were grouped: of the sons of Eleazar there were sixteen, all heads of families; and of the sons of Ithamar, heads of families, there were eight.

5 So they were put into groups, by the Lord's decision, one with another; for there were rulers of the holy place and rulers of the house of God among the sons of Eleazar and the sons of Ithamar.
