Ibn Ezra, Exodus 22:23
אבן עזרא, שמות כב:כג
ואחר שאמר לא תענון לשון רבים אמר אם... תענה, כי כל רואה אדם שהוא מענה יתום ואלמנה ולא יעזרם, גם הוא יחשב מענה:
After it says, "Do not oppress" in the plural the language changes to be singular..., for anyone who sees a person oppressing an orphan or a widow and does not come to their aid, they will also be considered oppressors. [AJWS translation]

Suggested Discussion Questions:

2. What injustices do you witness today? Are you responsible to fix them? How?
