עֲרֹ֣ב עַבְדְּךָ֣ לְט֑וֹב אַֽל־יַעַשְׁקֻ֥נִי זֵדִֽים׃
주의 종을 보증하사 복을 얻게 하시고 교만한 자가 나를 압박하지 못하게 하소서
Rashi
Rob me (עָשְׁקָה), like עֲשֹׁק. Rob me, take me out of the hand of the angel of death, and pledge Yourself to save me. This (עָרְבֵנִי) is an expression of surety (garantieh in O.F.). Comp. (Ps. 119) “Pledge Yourself (עֲרוֹב) to Your servant for good.”
Rashi
Tidings of their welfare. This is an expression of salvation, as in 'Assure your servant for good';11Tehillim 119:122.garantis in O.F. Our Rabbis said [it means] that he should take a divorce from them, and deliver it to their wives, to break the connection [עֵרוּב] between him [husband] and her [wife].12It was customary for soldiers to divorce their wives upon leaving for war. This was done to spare the wives from any difficulty to remarry in case they did not return. See Maseches Kesubos 9b and Maseches Shabbos 56a.
