וַיָּבֵ֣א הַסֵּ֔פֶר אֶל־מֶ֥לֶךְ יִשְׂרָאֵ֖ל לֵאמֹ֑ר וְעַתָּ֗ה כְּב֨וֹא הַסֵּ֤פֶר הַזֶּה֙ אֵלֶ֔יךָ הִנֵּ֨ה שָׁלַ֤חְתִּי אֵלֶ֙יךָ֙ אֶת־נַעֲמָ֣ן עַבְדִּ֔י וַאֲסַפְתּ֖וֹ מִצָּרַעְתּֽוֹ׃
Tomó también letras para el rey de Israel, que decían así: Luego en llegando á ti estas letras, sabe por ellas que yo envío á ti mi siervo Naamán, para que lo sanes de su lepra.
Rashi
I will heal the limping one Heb. אֹסְפָה. I will gather in the exiles. So did Jonathan render. To me, however, it appears as an expression of healing, as in (II Kings 5:6) “And you shall cure him (וְאֲסַפְתּוֹ) of his zaraath.”
Rashi
ואחר תאסף AND AFTER THAT LET HE BE GATHERED IN AGAIN — I say that all the different forms of the root אסף which are employed in reference to lepers (cf. e. g. 2 Kings 5:6, 11) are used because he (the leper) is sent forth from the camp and when he becomes healed he is taken again into the camp; — on this account it uses of him the term אסיפה, which has the meaning of “taking in” something that was outside.
