וְאֵ֛לֶּה שְׁמ֥וֹת בְּֽנֵי־אַהֲרֹ֖ן הַבְּכ֣וֹר ׀ נָדָ֑ב וַאֲבִיה֕וּא אֶלְעָזָ֖ר וְאִיתָמָֽר׃
아론의 아들들의 이름은 장자는 나답이요 다음은 아비후와 엘르아살과 이다말이니
Zohar
We have learned that it is written, "These are the names of the sons of Aaron, the priests" (Bemidbar 3:3) and also, "Nadab the firstborn, and Abihu, Elazar and Itamar" (Ibid. 2). It should read: 'And Elazar and Itamar" so why write "Elazar and Itamar?" (i.e. why delete the Vav). Abihu was equal to his two brothers and Nadab is equal to all the others.
