Parashat Shemot

Moses sees an Egyptian taskmaster killing a Hebrew slave, checks that no one is around and steps forward to intervene. The following day, a further encounter with two Hebrews reveals to Moses that someone had in fact seen him killing the Egyptian the previous day. Beneath the surface of this seeming contradiction within the story, lies the basis of a common psychological phenomenon regarding the duty upon each of us to act upon a sense of moral and social responsibility.
