Commentary for Taanit 45:12

ותגזר אומר אתה גזרת מלמטה והקדוש ברוך הוא מקיים מאמרך מלמעלה ועל דרכיך נגה אור דור שהיה אפל הארת בתפלתך

When they cast thee down, thou shalt say: There is lifting up:' You have raised with your prayer a generation that has sunk low.' For the humble person He saveth:' You have saved by your prayer a generation that is humiliated with sin.' He delivereth him that is not innocent:' You have delivered by your prayer a generation that is not innocent.'

Rashi on Taanit
