시편 118:18 미드라쉬: Mekhilta DeRabbi Yishmael & Midrash Tehillim

But if his master persecuted him and knocked out his tooth or blinded his eye or (maimed) one of his (other) external organ prominences, he acquires himself (i.e., his freedom) with afflictions. Now does this not follow a fortiori, viz.: If one can acquire himself by afflictions from the hand of flesh and blood, how much more so, from the hands of Heaven! And thus is it written (Psalms 118:18) "The L–rd has afflicted me exceedingly and He did not consign me to death."

"God chastises those He loves. Adversity is beloved since it is purifying, just as sacrifices are. Regarding sacrifices it is written (Leviticus 1:4) 'and it shall be accepted for him to atone for him'. Regarding adversity it is written (Proverbs 3:12) 'for whom the Lord loves, He admonishes'. Furthermore, adversity is even more beloved than sacrifices, as sin offerings and guilt offerings only atone for specific sins, as it is written 'and it shall be accepted for him to atone for him'. But adversity atones for everything. 'God, chastise me in Your discipline.'"
