Similarly, (Numbers 25:18) "Kazbi, the daughter of a prince of Midian, their sister." Now was she their (Midian's) sister? Was he (Tzur, her father,) not "the head of the peoples of a father's house in Midian" (viz. (Numbers 25:15)? Why, then, "their (Midian's) sister'? — Because she risked her life for her people, they were called by her name.
