תּוֹרָה רמא

When judgments are upon one person — G-d forbid — and another person comes and stands and disputes against him — then the attribute of judgment departs from him. For the person has more power to take revenge (see the main text). Therefore one who is a great Tzadik — watchful over the rectification of the world — sometimes intentionally disputes with one Tzadik in order to remove the attribute of judgment from him. But afterwards he acts with mercy and does not cause suffering to that Tzadik.
