אֶֽת־חֻקֹּתַי֮ תִּשְׁמֹרוּ֒ בְּהֶמְתְּךָ֙ לֹא־תַרְבִּ֣יעַ כִּלְאַ֔יִם שָׂדְךָ֖ לֹא־תִזְרַ֣ע כִּלְאָ֑יִם וּבֶ֤גֶד כִּלְאַ֙יִם֙ שַֽׁעַטְנֵ֔ז לֹ֥א יַעֲלֶ֖ה עָלֶֽיךָ׃ (פ)
Ustaw Moich przestrzegajcie; bydła twojego nie spuszczaj w rodzajach różnych, pola twojego nie obsiewaj gatunkiem mieszanym; a w szatę mieszaną z różnorodnej przędzy nie odziewaj się.
Mishnah Bikkurim
And how is [a koy] neither like a behemah nor like a hayyah?It is forbidden because of kilayim [to yoke it] with either a behemah or a hayyah. One who deeds his son his behemah and his hayyah he has not [thereby] given him the koy. If one says, “I will become a nazirite if this is [not] a hayyah or a behemah”, he is a nazirite. In all other ways it is like a behemah and a hayyah: It requires slaughtering (shehitah) like them both; It carries carrion impurity; And to it applies the law relating to a limb of a living being like them both.
