וְאָמַרְתָּ֣ אֵ֠לָיו הִשָּׁמֵ֨ר וְהַשְׁקֵ֜ט אַל־תִּירָ֗א וּלְבָבְךָ֙ אַל־יֵרַ֔ךְ מִשְּׁנֵ֨י זַנְב֧וֹת הָאוּדִ֛ים הָעֲשֵׁנִ֖ים הָאֵ֑לֶּה בָּחֳרִי־אַ֛ף רְצִ֥ין וַאֲרָ֖ם וּבֶן־רְמַלְיָֽהוּ׃
Y dile: Guarda, y repósate; no temas, ni se enternezca tu corazón á causa de estos dos cabos de tizón que humean, por el furor de la ira de Rezín y del Siro, y del hijo de Remalías.
Rashi on Isaiah
Feel secure Heb. הִשָּׁמֵר. Sit tranquilly like wine on its lees (שְׁמָרָיו).
Ibn Ezra on Isaiah
חִשָּׁמֵ֨ר Accent on the last syllable. This word is to be compared with שמרים dregs, lees (25:6.), שמריו ושקם הוא על He has settled on his lees (Jerem. 48:11), and explained, Remain on thy lees (that is remain quiet), for הִשָּֽׁמֶר Take heed has the accent on the last syllable but one; and besides, the following Fear not proves the correctness of this explanation.4השמר is parallel to אל הירא as השקט to לבבך אל ירך, and all these verbs appear to have a similar meaning, while Take heed, and Fear not are just the reverse in meaning the one of the other. השמר means therefore, according to I. E., remain quiet.
Rashi on Isaiah
smoking stubs of firebrands Consider them as stubs of firebrands whose flame has been extinguished. אוּדִים is tisons [embers] in French.
