"VaYamos Nadav Vavihi... OoVanim Lo Hoyu Lahem: And Nadav and Avihu died... and they had no children" Why does it say "VaYamos" - "and he died" - in the singular, instead of "Vayamusu" - "and they died" - in the plural?
According to the Zohar, before a person marries, he is considered a half person. After acquiring a wife, he becomes a complete entity. At the time of their death, Nadav and Avihu were both single, and therefore each was only considered one half. Thus, together they totaled only one.
