What does it mean to not cast your pearls before swine (Matthew 7:6)?

WHAT DOES THE BIBLE SAY?

Jesus’ command not to cast pearls before swine (Matthew 7:6) is a call to value God’s truth and share it with discernment. In His cultural context, “dogs” and “swine” represented those who were unclean and, more specifically, those who were hostile toward what is holy. The “pearls” symbolize the precious truth of God—something of immense worth that should not be treated casually. Jesus warns that some people will not only reject that truth but will trample it and turn against the one offering it. This does not cancel the call to share the gospel (Matthew 28:19–20), but it clarifies that wisdom must guide how and when we do so. The Old Testament echoes this principle, warning that correcting a scoffer often invites hostility rather than repentance (Proverbs 9:7–8; 23:9). Jesus uses this word picture to teach that faithful witness requires both boldness and discernment—knowing when to persist and when to step back, trusting God to work in hearts in His time.

FROM THE OLD TESTAMENT

• In the Old Testament, God forbade the eating of certain animals, particularly pigs, which came to represent uncleanliness (Leviticus 11:7). Jesus intentionally referenced swine to draw on this connotation of uncleanliness.
• From the Old Testament, we also learn that we must use wisdom when responding to someone’s arguments against the truth. Proverbs 9:7–8 illustrates this, saying, “Whoever corrects a scoffer gets himself abuse, and he who reproves a wicked man incurs injury. Do not reprove a scoffer, or he will hate you; reprove a wise man, and he will love you.” Correcting someone with the truth is not the problem, but a scoffer, someone who actively hates the truth, will just throw it back at the one trying to help.
• God’s wisdom and truth are valuable and worth guarding. While everyone can benefit from the truth, it must not be wasted on those who will simply trample on it: “Do not speak in the hearing of a fool, for he will despise the good sense of your words” (Proverbs 23:9).

FROM THE NEW TESTAMENT

• The immediate context of Matthew 7:6 is known as the “Sermon on the Mount.” There, Jesus is providing various bits of wisdom and guidance for believers on how to live rightly in and for the kingdom of God.
• It is in that context that Jesus says, “Do not give dogs what is holy, and do not throw your pearls before pigs, lest they trample them underfoot and turn to attack you” (Matthew 7:6). The meaning of “pigs” is clear from the Old Testament context of pigs representing unclean animals. “Dogs” later became a Jewish slur for Gentiles. Because Gentiles were “unclean” by Jewish standards, the words “dog” and “pig” were references to uncleanliness.
• However, Jesus was not using them in the derogatory ways that Jews used them. Instead, He broadened them to refer to those who were rabidly against the truth. While all unbelievers are, in some sense, “unclean,” those like the Pharisees actively pursued those who taught the truth. Jesus was talking about those hateful unbelievers.
• A “pearl” was an extremely valuable thing in Jesus’ day. Jesus said that the pearls represent “what is holy,” namely, what is true. So, “pearls” represent God’s wisdom and truth. In saying not to cast pearls before swine, Jesus was saying that giving truth to someone rabidly opposed to it is like throwing your most valuable item to pigs who have no appreciation for its value. All they will do is crush them into the ground as if they were useless. Likewise, those who are strongly opposed to the truth will discard any pearls of wisdom given to them.
• Worse than simply wasting time, Jesus comments that the hard pearls under the pigs' feet only make them angry, and they will attack. Likewise, those opposed to the truth will often turn and attack anyone who tries to help them by sharing God’s valuable truth. Knowing when to share the truth and when not to requires discernment. Jesus clearly taught that believers are to go into the world and share the gospel (Matthew 28:19–20). And yet, at the same time, they were to use wisdom to know when to reject those who rejected the truth (Matthew 10:14).

IMPLICATIONS FOR TODAY

Being a Christian requires ongoing discernment throughout life, and this is also true when it comes to sharing the gospel. Jesus taught us to be both “innocent as doves and wise as serpents” (Matthew 10:16). He knew that the world was a hard place and that persecution would come to His disciples. So, while we are to be loving and kind to all, and while we are called to share the gospel, we are to know when to share it and when we are to stop and look for another opportunity.

Everyone is sinful, but how that sin expresses itself varies widely from person to person. Some unbelievers will listen and even converse with you with great patience. However, on the other end of the spectrum, some are looking for every opportunity to throw what you said back in your face. While you may truly be loving them by trying to warn them of eternal damnation, they are like the swine who trample on those pearls of wisdom, become enraged, and turn to attack you.

This does not mean you should fear sharing the truth. Nor does it mean you stop speaking to them purely for personal comfort. But when you realize your effort is being wasted on them, it’s better to prioritize those who want to listen. At times, it becomes clear that the one we are speaking with is only enraged by what we say. That doesn’t mean that God might not save them later, but it may mean that, for now, we need to pull back. If God intends to save that individual, we can trust that He will do the work in their heart necessary so that, in the future, they will listen and respond.

UNDERSTAND

• "Dogs" and "swine" refer to unbelievers who are rabidly hostile to God's truth, actively attacking those who share it.
• Casting pearls before swine means offering God's truth to those who will not only reject it but trample it and turn on the one sharing it.
• Believers are called to share the gospel boldly while exercising the discernment to recognize when continued engagement with hostile individuals is unwise.

REFLECT

• How do you currently exercise discernment in deciding when to continue sharing truth with someone who is resistant versus when to step back?
• In what ways are you tempted to either share truth indiscriminately without wisdom or to withhold it out of fear rather than genuine discernment?
• How does knowing that God is ultimately responsible for opening hearts to the truth free you from feeling like you have failed when someone rejects the gospel?

ENGAGE

• How do we practically distinguish between someone who is genuinely resistant to the truth and someone who is simply not yet ready to receive it?
• What does Jesus' own example of engaging some hostile audiences while withdrawing from others teach us about the balance between persistence and discernment in evangelism?
• How should the principle of casting pearls before swine inform the way churches and individual believers approach evangelism strategies in their communities?
