This week's portion opens with the laws of commitments, oaths, promises, and pledges. In Judaism, one’s word is one’s word. Deviating from one’s word or other commitment is considered to be an especially grave offense in Judaism.
This week’s Torah portion, Korach, is named after one of the biggest trouble makers of all time. Korach started a rebellion against the leadership of Moses. Of course, Moses, being the appointed leader of God, emerged victorious, while Korach and his followers were swallowed up by an earthquake.
