Kapparos or Kaparot (Hebrew: כפרות‎, "atonements") is a traditional Jewish animal sacrifice that takes place on the eve of Yom Kippur. Classically, it is performed by grasping a live chicken by the shoulder blades and moving around one's head three times, symbolically transferring one's sins to the chicken. The chicken is then slaughtered and donated to the poor, preferably eaten at the pre-Yom Kippur feast. Preferably, a man should use a rooster, and a woman should use a hen for the ritual. The ritual is preceded by the reading of Psalms 107:17-20 and Job 33:23-24.
