וַיָּ֣מָת נָדָ֣ב וַאֲבִיה֣וּא לִפְנֵ֣י יְהוָ֡ה בְּֽהַקְרִבָם֩ אֵ֨שׁ זָרָ֜ה לִפְנֵ֤י יְהוָה֙ בְּמִדְבַּ֣ר סִינַ֔י וּבָנִ֖ים לֹא־הָי֣וּ לָהֶ֑ם וַיְכַהֵ֤ן אֶלְעָזָר֙ וְאִ֣יתָמָ֔ר עַל־פְּנֵ֖י אַהֲרֹ֥ן אֲבִיהֶֽם׃ (פ)
И умерли Надав и Авиху пред Господом, когда предали странный огонь пред Господом в Синайской пустыне, и не имели детей; Елеазар и Ифамар служили в священнике'Офис Аарона в присутствии их отца.
Zohar
Another interpretation is as follows. R. Jose said: ‘Why does the text say, “after the death of the two sons of Aaron”, and not “after the death of Nadab and Abihu”, since we know they were his sons? The reason is to show that they had not yet emerged from the guardianship of their father, but they thrust themselves forward in his lifetime.’
