וַיֹּ֣אמֶר יְשַׁעְיָ֔הוּ יִשְׂא֖וּ דְּבֶ֣לֶת תְּאֵנִ֑ים וְיִמְרְח֥וּ עַֽל־הַשְּׁחִ֖ין וְיֶֽחִי׃
Ora Isaías dissera: Tomem uma pasta de figos, e a ponham como cataplasma sobre a úlcera; e Ezequias sarará.
Radak
וחיה, as if the Torah had written ותחיה “and you will live.” The construction is parallel to Genesis 12,3 והיה ברכה, “you will become a source of blessing. The verb ותרפא is in a “weak” mode as in Joshua 5,8 עד חיותם, ”until they have re- covered.” We find a similar construction in Isaiah 38,21 וימרחו על השחין ויחי, “if they will smear it on the rash he will recover.”
