אֵ֗לֶּה שְׁמוֹת֙ בְּנֵ֣י אַהֲרֹ֔ן הַכֹּהֲנִ֖ים הַמְּשֻׁחִ֑ים אֲשֶׁר־מִלֵּ֥א יָדָ֖ם לְכַהֵֽן׃
이는 아론의 아들들의 이름이며 그들은 기름을 발리우고 거룩히 구별되어 제사장 직분을 위임받은 제사장들이라
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.
