In his commentaries, Rashi displays great sensitivity towards the people in society who are indigent or powerless, who have no defenders.  This compassion for the disadvantaged is expressed in numerous ways.

Rashi expresses great affection for the forebears of Israel, the Patriarchs, the Matriarchs, and the Twelve Tribes. This regard is expressed in two areas.  The first is an attempt to minimize — to the level of obscuring the very progression of the biblical text — the negative traits or acts which are attributed in Scripture to Israel’s forebears and its role models. The second is the glorification of acts that seem to be insignificant.
