Commentary for Kiddushin 71:18

הגשות דכתיב (ויקרא ו, ז) וזאת תורת המנחה הקרב אותה בני אהרן בני אהרן ולא בנות אהרן

For should you reply, only when foolish are they designated sons, but not when they lack faith - then come and hear: And it is said: 'They are sons in whom is no faith'. And should you say, when they have no faith they are called sons, but when they serve idols they are not called sons - then come and hear: And it is said: 'a seed of evil-doers, sons that deal corruptly.'
