Variantly: "Honor your father and your mother': (Leviticus 19:3) "A man, his mother and his father shall you fear," this tells me only of a man. Whence do I derive (the same for) a woman/ Whence do I derive (the same for) a tumtum (one of indeterminate six) or a hermaphrodite? It is, therefore, written "Honor your father and your mother," — in any event. Just as with honor (of parents) there is no distinction between a man or a woman, so, with fear.
