מִכְתָּ֖ב לְחִזְקִיָּ֣הוּ מֶֽלֶךְ־יְהוּדָ֑ה בַּחֲלֹת֕וֹ וַיְחִ֖י מֵחָלְיֽוֹ׃
אַ געשריפֿטס פֿון חִזקִיָהו דעם מלך פֿון יהוּדה, װען ער איז קראַנק געװען, און איז גענעזן געװאָרן פֿון זײַן קראַנקשאַפֿט.
Rashi
The writing of Hezekiah Jonathan paraphrases: A writing of thanksgiving for the miracle performed for Hezekiah.
Ibn Ezra
ויחי And was recovered. Comp. עד חיותם till they were whole (Jos. 5:8), ואתה מחיה and thou preservest (Neh. 9:6). It might also mean, And he lived.1In this case the word מחליו which follows, must be translated: his illness being no more, or after having been ill.
