להבדיל TO MAKE A DISTINCTION — Not that one should only learn the laws, but it is a command that you should know and recognize the differences and be expert in them (Sifra, Shemini, Chapter 12 6). ‎הטהור‎‎ בין הטמא ‎ובין‎ BETWEEN THE UNCLEAN AND THE CLEAN — Is it necessary to say. that one should understand to distinguish between the ass and the cow? Have they not already been closely defined as to their distinguishing characteristics? But the meaning is: that you should thoroughly understand to distinguish between what is unclean for you and what is clean for you (i. e. between what is forbidden and what is permitted to you) — between the case of an animal only half of whose wind-pipe has been cut through by the knife, and the case when the greater part has been cut through (in the former case the animal is forbidden, in the latter it is permitted as food) (Sifra, Shemini, Chapter 12 7). ובין החיה הנאכלת AND BETWEEN AN ANIMAL THAT MAY BE EATEN — Is it necessary to say that one should learn to distinguish between a stag and a wild ass? Have not these already been closely defined as to their distinguishing characteristics? But the meaning is: that you should thoroughly understand to distinguish between the case when there have arisen in it (in the animal) signs by which one might regard it as forbidden (טרפה) and yet it is permitted as food (כשרה), and the case when there have arisen in it signs by which one might regard it as forbidden and because of which it is actually unfitted to be eaten (Sifra, Shemini, Chapter 12 8).

לְהַבְדִּ֕יל בֵּ֥ין הַטָּמֵ֖א וּבֵ֣ין הַטָּהֹ֑ר וּבֵ֤ין הַֽחַיָּה֙ הַֽנֶּאֱכֶ֔לֶת וּבֵין֙ הַֽחַיָּ֔ה אֲשֶׁ֖ר לֹ֥א תֵאָכֵֽל׃ {פ}

to make a distinction between the unclean and the clean, and between the beast that may be eaten and the beast that may not be eaten.
