What does the phrase "Cast the first stone" warn against?

The phrase "Cast the first stone" originates from the Bible, specifically from the story in the Gospel of John, where Jesus says, "He who is without sin among you, let him cast the first stone." This statement warns against hypocrisy and judgment because it emphasizes that individuals should not condemn others for their faults unless they themselves are free from similar faults. The underlying message is that everyone has their own shortcomings and that passing judgment on others can often reflect one's own moral failings.

In this context, the choice related to hypocrisy and judgment is correct because it highlights the moral lesson about recognizing one's own imperfections before criticizing others. The phrase serves as a reminder to approach others with compassion rather than condemnation, which is crucial in fostering understanding and mercy among people.
