What does 'don't cast your pearls before swine' mean?A Scripture-grounded answer about don't cast your pearls before swine

The phrase pearls before swine comes from Jesus' Sermon on the Mount in Matthew 7:6. In the ancient world, pearls were among the most precious treasures, while pigs were considered unclean animals that could not appreciate their value. Jesus uses this vivid image to teach spiritual discernment in sharing faith—sacred truths should be shared generously, but believers must recognize when an audience is not merely indifferent but actively hostile and determined to trample underfoot what is offered. This is not a call to be elitist or withhold the gospel; earlier in the same sermon Jesus commands love for enemies. Rather, it is practical wisdom about stewardship of holy things. Proverbs 9:8 echoes this: do not rebuke a mocker or he will hate you. The apostle Paul modeled this in Acts 13:46, turning from those who rejected the message to others who were eager to hear. The principle calls for discernment—reading situations wisely, knowing when to persist and when to move on, trusting the Holy Spirit to prepare hearts.
