The next morning, Jesus returned to the temple and the people came to hear what He had to say. As He was teaching, the scribes and Pharisees attempted to trap Him into saying something they could use against Him. They thought He would either speak against the Law of Moses or violate the Roman government. He did neither.
According to the Law of Moses, adultery was punishable by stoning a person to death and they had brought a woman caught in the act. Since the Law required the witnesses to cast the first stone, Jesus instructed the one who was without sin to cast a stone at her first.
Convicted of their own sins, they all left—from the oldest to the youngest. Jesus did not approve of the woman’s sin, but forgave her and told her to “Go and sin no more.”
