וַיְהִ֛י כַּאֲשֶׁר־תַּ֥מּוּ כָל־הַגּ֖וֹי לְהִמּ֑וֹל וַיֵּשְׁב֥וּ תַחְתָּ֛ם בַּֽמַּחֲנֶ֖ה עַ֥ד חֲיוֹתָֽם׃ (פ)
E avvenne che, quando tutta la nazione ebbe finito di farsi circoncidere, rimasero al loro posto nell'accampamento finché non furono guariti.
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.”
Sforno
וחיה, and be healed and stay alive; we find a similar construction in Joshua 5,8 עד חיותם, “until they have been healed.”
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.
