The story of the Good Samaritan is one of the most well-known and loved Bible stories. Many children learn it in Sunday school as a wonderful example of how to be kind and caring to others. And indeed, in the story we see the priest and temple helper fail to show compassion to the badly beaten man. But we see the Samaritan go above and beyond the call of duty to ensure the beaten man has every chance of recovery.
What we may not have realized, however, is that the priest and temple helper were actually prohibited by the law of Moses to go and touch the beaten man. Because he had been left for dead, if these servants of God had touched him, they would have been made unclean and incapable of fulfilling their roles in the worship at the temple.
