Talmud su II Samuele 13:29

³⁹Tosephta Kilaim 5:6. The Tosephta rejects Issi’s argument since it is written about David that he did all Eternal (1K. 15:5). Issi ben Aqabia⁴⁰A Tanna of the last generation, student of R. Eleazar ben Shamua and R. Yose, who appears also as Issi ben Gur Arieh, Issi ben Jehudah, Issi ben Gamliel, Joseph the Babylonian, Joseph from Hutsal, and maybe Rav Assi. says: It is forbidden to ride on a mule by an argument of analogy. If garments which you may wear one upon the other are forbidden in mixture⁴¹It might be permitted to wear a woolen coat over a linen garment but it is forbidden to wear any garment containing both wool and linen; cf. Chapter Nine, end of Halakhah 7., you are certainly forbidden to ride on [a mixture of] animals you may not lead together. But is it not written (2Sam. 13:29): “Each one rode on his mule and they fled”? One does not learn from a king’s family⁴²They will not listen to religious authority.. But is it not written (1K. 1:33): “Let my son Solomon ride on my she-mule”? That was a creature from Creation⁴³A wild animal, spontaneous offspring of a wild horse and a wild ass..
