פּירוש אויף ישעיהו 54:12

“I will make your pinnacles of rubies, etc.” [54:12]. I will make your windows so that the sun will shine in and will illumine large pearls within, and your gate will shine brightly with precious stones, like a flame. All the stones that were found in your boundaries will now become precious stones and pearls.

jasper Heb. כַּדְכֹד, a kind of precious stone.

כדכד Agates. It is hap. leg.; it is the name of a precious stone.

your windows Jonathan renders: your woodwork, and Menahem associated it with (Dan. 7:10): “ministered to Him (יְשַׁמְּשׁוּנֵהּ).” (Menahem, apparently renders: your utensils, i.e., the vessels that serve you.) And some interpret it as an expression of a sun (שֶׁמֶשׁ), windows through which the sun shines, and they make opposite it a barrier of kinds of colored glass for beauty, and Midrash Psalms interprets שִׁמְשׁוֹתַיִךְ as well as שֶׁמֶשׁ וּמָגֵן (Ps. 84:12) as “the pinnacles of the wall.”

of carbuncle stones Heb. אֶקְדָּח. Jonathan renders: of gomer stones. Gumrin is the Aramaic translation of גֶּחָלִים, coals. He interprets אֶקְדָּח as an expression similar to (supra 50: 11) “who kindle (קֹדְחֵי) fire,” and they are a type of stones that burn like torches and that is the carbuncle (karbokle in O.F.), an expression of a coal. Others interpret it as an expression of a drill, i.e., huge stones of which the entire opening of the doorway is drilled, and the doorposts, the threshold, and the lintel are all hewn from the stone.
