ה֤וֹי כָּל־צָמֵא֙ לְכ֣וּ לַמַּ֔יִם וַאֲשֶׁ֥ר אֵֽין־ל֖וֹ כָּ֑סֶף לְכ֤וּ שִׁבְרוּ֙ וֶֽאֱכֹ֔לוּ וּלְכ֣וּ שִׁבְר֗וּ בְּלוֹא־כֶ֛סֶף וּבְל֥וֹא מְחִ֖יר יַ֥יִן וְחָלָֽב׃
ç vós, todos os que tendes sede, vinde às águas, e os que não tendes dinheiro, vinde, comprai, e comei; sim, vinde e comprai, sem dinheiro e sem preço, vinho e leite.
Rashi on Isaiah
Ho! All who thirst Heb. הוֹי. This word הוֹי is an expression of calling, inviting, and gathering, and there are many in Scripture, [e.g.,] (Zech. 2:10) “Ho! Ho! and flee from the north land.”
Ibn Ezra on Isaiah
הוי Ho ! It is the sign of the vocative. Ho, every one that thirsteth, etc. With these words the Lord will address those who will then be desirous to accept the Law.
