What does the Bible say about casting pearls before swine?

In Matthew 7:6, Jesus instructs His followers not to give what is holy to dogs or cast pearls before swine. This admonition emphasizes the importance of discerning the audience when sharing the gospel and spiritual truths. Holy things, such as the gospel and its ordinances, are intended for those who are spiritually receptive—God's chosen people—while those described as dogs or swine are unregenerate and hostile to the truth. This scripture serves as a reminder that sharing sacred truths with those who cannot comprehend or value them is not only fruitless but can also lead to contempt or harm.
