Parallel
Numbers 3:4
Brenton's English Septuagint · Berean Standard Bible
And Nadab and Abiud died before the Lord, when they offered strange fire before the Lord, in the wilderness of Sina; and they had no children; and Eleazar and Ithamar ministered in the priests' office with Aaron their father.
Nadab and Abihu, however, died in the presence of the LORD when they offered unauthorized (note: Or strange) 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.
