אַל־תִּבָּהֵ֤ל מִפָּנָיו֙ תֵּלֵ֔ךְ אַֽל־תַּעֲמֹ֖ד בְּדָבָ֣ר רָ֑ע כִּ֛י כָּל־אֲשֶׁ֥ר יַחְפֹּ֖ץ יַעֲשֶֽׂה׃
No te apresures á irte de delante de él, ni en cosa mala persistas; porque él hará todo lo que quisiere:
Tosafot Yom Tov
HE USED TO SAY: AT FIVE YEARS OLD, ETC. Other versions do not have this mishna. Midrash Shmuel writes in the name of R. Yehuda bar Shlomo that these are not the words of R. Yehuda ben Teima and are not part of this tractate. They are the words of Shmuel HaKatan that the Sages have appended here, and some versions have written here the mishna in 4:19, “Shmuel HaKatan says, do not rejoice at the fall of your enemy, etc.”
At the beginning of the following mishna, he writes that some editions have this as the last mishna in the tractate. But this does not seem reasonable, for the tractate would not end with talk of dying and ceasing from the world; we find that the tannaim are very particular about this, as they said (Kelim 30:4), “praiseworthy are you, Kelim, for you started with purity and ended with purity”, and did likewise at the end of tractate Yadayim,236Which quotes Pharaoh refusing to send the Israelites out of Egypt, and then mentions Pharaoh saying that G-d is righteous to end on a good note. all because of “do not stop at a bad thing” (Ecclesiastes 8:3).
