Talmud zu Schemot 29:23

Rebbi Abba, Rebbi Ḥiyya in the name of Rebbi Joshua ben Levi: Nothing is clear except the seven fluids⁴¹The 7 fluids enumerated in Mishnah Makhširin 6:4: Dew, water, wine, oil, blood, milk, bee’s honey.. Rebbi Yose asked: Was this said for ḥallah⁴²Does R. Joshua ben Levi disagree with the Mishnah and hold that only dough kneaded with one of the 7 fluids is subject to ḥallah? or for impurity? If you say for ḥallah, so much more for impurity. If you say for impurity, then not for ḥallah. It is obvious for Rebbi Jonah that it had been said for ḥallah, so much more for impurity. Rebbi Jonah sticks to his opinion, for Rebbi Jonah stated from Rebbi Simeon ben Ioḥai; Rebbi Joshua ben Levi stated in Rebbi Simeon ben Ioḥai’s name, as Rebbi Simeon ben Ioḥai stated: Rebbi Ṭarphon said, it is stated here⁴³Num. 15:20. ḥallah, and it is stated there⁴⁴Lev. 8:26. About the theory of invariable meaning of words, cf. Kilaim8, Note 4., a ḥallah of oil cake. Since the ḥallah mentioned there is prepared with oil, so the ḥallah prepared here must be prepared with oil. And oil is one of the seven fluids.
