וְאַתָּה֙ כִּֽי־הִזְהַ֣רְתָּ רָשָׁ֔ע וְלֹא־שָׁב֙ מֵֽרִשְׁע֔וֹ וּמִדַּרְכּ֖וֹ הָרְשָׁעָ֑ה ה֚וּא בַּעֲוֺנ֣וֹ יָמ֔וּת וְאַתָּ֖ה אֶֽת־נַפְשְׁךָ֥ הִצַּֽלְתָּ׃ (ס)
但你若警告了惡人，他卻不回轉離開他的惡行和他的惡道，他必因自己的罪孽而死；而你卻救了自己的性命。
Rashi
the shamir and desolation will come up Heb. שָׁמִיר וָשָׁיִת. Menahem ben Seruk interprets them as kinds of thorns (Machbereth Menahem p. 176), but I say that “shamir” is a word denoting a strong worm that splits stones, with which Solomon built the Temple, like the matter that is written (Ezekiel 3:19), “Like a shamir, stronger than rock.”
