פּירוש אויף ישעיהו 1:4

ה֣וֹי ׀ גּ֣וֹי חֹטֵ֗א עַ֚ם כֶּ֣בֶד עָוֺ֔ן זֶ֣רַע מְרֵעִ֔ים בָּנִ֖ים מַשְׁחִיתִ֑ים עָזְב֣וּ אֶת־יְהוָ֗ה נִֽאֲצ֛וּ אֶת־קְד֥וֹשׁ יִשְׂרָאֵ֖ל נָזֹ֥רוּ אָחֽוֹר׃

װײ, זינדיקע אומה, פֿאָלק מיט פֿאַרברעכן באַשװערט, זאָמען פֿון שלעכטסטוער, קינדער פֿאַרדאָרבענע! פֿאַרלאָזט האָבן זײ גאָט, געלעסטערט דעם הײליקן פֿון ישׂראל, אַהינטער זיך אָפּגעקערט.

Rashi

Woe Every instance of הוֹי in Scripture is an expression of complaining and lamenting, like a person who sighs from his heart and cries, “Alas!” There are, however, several, which are an expression of a cry, the vocative voice, e.g., “Ho, ho, flee from the land of the north” (Zech. 2:10), which the Targum renders, אַכְלוּ, an expression of announcing. Woe There is a reason to cry about a holy nation that turned into a sinful nation, and a people referred to by the expression, “for you are a holy people” (Deut. 7:6), turned into a people with iniquity.

Ibn Ezra

הוי. Some consider the ה as a substitute for א, and explain אוי ═ הוי, ‘woe;’ comp. אדורם and הדורם, N. pr. (2 Chr. 10:18; 1 Kings 12:18); איך and היך, how (1 Chr. 13:12 ; 2 Sam. 6:9); but I think that it is a sign of the vocative case (derived from the verb היה ‘to be’), and that the passage must be rendered, O sinful people, etc. ; comp. הוי הוי ונסו, Ho, ho, flee (Zach. 2:10), הוי ציון המלטי O Zion, deliver thyself (Ibid. 11).13In the two passages quoted by the author, הוי cannot be translated by ‘ woe,’ because it is followed by good tidings.—Ibn Ezra does not mean to say that הוי is never used instead of אוי (woe); for in this same chapter (ver. 24) he admits the identity of these two words.—The connection between היה ‘ to be ’ and הוי ‘ Oh ’ is not clear. Comp. Zahoth, On the Aleph. The second person is, therefore, used in the next verse, Why should ye be stricken any more.

Rashi

they drew backwards [The root נְזִירָה,] wherever it appears, is only an expression of separation. Similarly, Scripture states: “And they shall separate (וְיִנָּזְרוּ) from the holy things of the children of Israel” (Lev. 22:2), “the one separated (נְזִיר) from his brothers” (Gen. 49:26). Here too, they drew away from being near the Omnipresent.
