וַיְהִ֛י כַּאֲשֶׁר־תַּ֥מּוּ כָל־הַגּ֖וֹי לְהִמּ֑וֹל וַיֵּשְׁב֥וּ תַחְתָּ֛ם בַּֽמַּחֲנֶ֖ה עַ֥ד חֲיוֹתָֽם׃ (פ)
И было, когда весь народ был обрезан, каждый из них, что они жили в своих местах в лагере, пока они не были целы.
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.
