Tosefta sobre Levítico 21:1

The ways in which he is like men: He imparts impurity with white discharge like men. He marries but is not married (נישא not נושא), like men. And he may not seclude himself with women, like men. And he is not provided sustenance (ניזון not נתזן) along with [a person's] daughters, like men. And he does not [permit himself to] become impure by the dead, like men (i.e., male priests). He is subject to transgressing the prohibition against "rounding off [the corners of the head]" (Lev. 19:27) and [if he is a priest] he is subject to transgressing the prohibition against "defiling oneself with the dead" (Lev. 21:1), like men, and he is liable for performing all the commandments in the Torah, like men.
