Several challenges are raised against Shila's interpretation of Rabbi Eliezer, who prohibits purchasing a red heifer from pagans based on a drasha on the word "vayikchu." The well-known story of Dama ben Netina—a non-Jew highlighted as a model for honoring one's parents, illustrating the extent to which one must go to fulfill this mitzva—is cited in objection. This story raises questions both about Shila's interpretation and about the alternative explanation that Rabbi Eliezer prohibits the purchase due to concerns about bestiality. Either way, if purchasing from pagans is not permitted, how did the rabbis intend to acquire the red heifer from Dama? Additional difficulties are posed against Rabbi Eliezer's ruling that animals may not be purchased from pagans for sacrificial purposes.
