כְּשָׁמִ֛יר חָזָ֥ק מִצֹּ֖ר נָתַ֣תִּי מִצְחֶ֑ךָ לֹֽא־תִירָ֤א אוֹתָם֙ וְלֹא־תֵחַ֣ת מִפְּנֵיהֶ֔ם כִּ֛י בֵּֽית־מְרִ֖י הֵֽמָּה׃ (פ)
Tulad ng matigas na bakal na higit na matigas kaysa sa batong-kiskisan, ginawa Kong gayon ang iyong noo. Huwag kang matakot sa kanila, at huwag kang manlupaypay sa harap nila, sapagkat sila ay isang sambahayang mapaghimagsik.”
Rashi
with a pen of iron This is an allegory. That is to say that it is deeply engraved, and cannot be erased. And the Midrash Aggadah explains: with a pen of iron, with a diamond point, preserved by Jeremiah, called ‘an iron wall,’ and by Ezekiel, to whom it was said (3:9): “As a diamond, harder than flint have I made your forehead.”
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.”
Chizkuni
צר, a sharp scalpel. Compare Joshua 5,2 חרבות צורים, according to Rash’bam. An alternate interpretation: the word צר means “stone;” we find it as having this meaning also in Ezekiel 3,9: כשמיר חזק מצור, like a shamir, “even harder than rock.” She took what was at hand.
