Jesus encounters a woman caught in adultery and brought before him by scribes and Pharisees who want to trap him. He tells those without sin to cast the first stone, causing them to leave one by one. When alone with the woman, Jesus tells her he does not condemn her but instructs her to sin no more. The lesson emphasizes that we have all sinned but God sent Jesus not to condemn but to save through forgiveness of sins for those who repent and obey.
