"My rebbi, Rav Pam, used to say that when one sees a child in pain, there is an issur of haalama;
one may not avert one's gaze from a lost object. Rav Pam would say that one who chooses to focus on the lost object-in this case, a Jewish child- can merit the mitzvah at the pasuk's end:
Hasheiv teshiveim, return it to its owner.
You can give a Yiddishe kind
back to his father and mother."
Dr. David Pelcovitz, quoted in "Facing the Challenges, Focusing on the Blessings," Yisroel Besser, Mishpachah, March 25, 2009
