לֹֽא־תַחֲרֹ֥שׁ בְּשׁוֹר־וּבַחֲמֹ֖ר יַחְדָּֽו׃ (ס)
Non arare insieme un bue e un asino.
Zohar
You may say that he gained nothing, but he said to him, "and I have oxen and donkeys" (Beresheet 32:6). These are sentences of judgment, that is, demons. When these two collaborate, they cooperate to harm the world, meaning it is not their nature to inflict damage except when they are joined. For this reason, it is written, "You shall not plow with an ox and a donkey together" (Devarim 22:10). (For this causes these two demons, namely the ox and the donkey, to be joined, and to inflict damage on the world).
