וַיֹּ֣אמֶר יְשַׁעְיָ֔הוּ יִשְׂא֖וּ דְּבֶ֣לֶת תְּאֵנִ֑ים וְיִמְרְח֥וּ עַֽל־הַשְּׁחִ֖ין וְיֶֽחִי׃
At sinabi ni Isaias: “Kunin nila ang isang tinapay ng pinatuyong igos at itapal nila ito sa pigsa, at siya ay gagaling.”
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.”
