אֲשֶׁ֨ר עָשָׂ֥ה דָוִ֛ד אֶת־הַיָּשָׁ֖ר בְּעֵינֵ֣י יְהוָ֑ה וְלֹֽא־סָ֞ר מִכֹּ֣ל אֲשֶׁר־צִוָּ֗הוּ כֹּ֚ל יְמֵ֣י חַיָּ֔יו רַ֕ק בִּדְבַ֖ר אוּרִיָּ֥ה הַחִתִּֽי׃
sapagkat ginawa ni David ang matuwid sa paningin ng Walang-Hanggan, at hindi siya lumihis sa anumang iniutos Niya sa kanya sa buong panahon ng kanyang buhay, maliban lamang sa usapin ni Urias na Hiteo.
Tosefta Kilayim
A horse may not be tied to a mule, or a mule to a donkey, or a donkey to a wild ass, because this one may be driven with that one. If he [nonetheless] did so, Rabbi Meir holds him liable, and the Sages exempt him. Rabbi Yehuda says, the offspring of a female horse and the offspring of a female donkey are forbidden [to be tied] together, but the sages say, all mules are a single species. Assi the Babylonian says, it is forbidden to ride on the back of a mule, from a kol v'chomer: Just as where it is permitted to wear two cloaks on top of one another [even if one is made of wool and the other of linen], yet it is forbidden [to wear a single cloak] if it is of a forbidden mixture, thus where it is forbidden to drive two [diverse species] together, does it not all the more so stand to reason that a forbidden mixture of both them should be forbidden? They said to him, behold, it says (1 Kings 1:33, JPS tr.), "and have my son Solomon ride on my mule, and bring him down to Gihon." He said to them, one cannot derive [halacha] from [actions performed] in urgency. They said to him, it says [as to Solomon] (2 Kings 18:3), "He did what was correct in the eyes of God, like all that his father David had done, and [as to David] (1 Kings 15:5), "He never turned throughout his life from all that had been commanded him [except in the matter of Uriah the Hittite]."
