Phylacteries in Matthew 23:5: Why Jesus Warned the Crowds
Short answer: Phylacteries were small leather boxes containing written Scripture, worn by Jewish men on the left arm and on the forehead. They were a literal way of keeping commands like Deuteronomy 6:8, which says, "You shall bind them for a sign on your hand, and they shall be for frontlets between your eyes." In Matthew 23:5 Jesus said of the scribes and Pharisees, "But they do all their works to be seen by men. They make their phylacteries broad, enlarge the fringes of their garments." His complaint was not that the boxes existed, but that they were enlarged as a performance for human applause. The issue was motive and display, not the object itself.
What a phylactery actually was
The word phylactery comes from a Greek term meaning a safeguard or protection, and by the first century it referred to tefillin, the paired leather boxes worn by observant Jewish men. Each box held small parchment strips inscribed with four passages from the Law: Exodus 13:1-10, Exodus 13:11-16, Deuteronomy 6:4-9, and Deuteronomy 11:13-21. One box was strapped to the upper left arm so that it rested against the heart, and the other was bound above the forehead. The straps were knotted in a fixed pattern. These were not magical amulets in their original intent, though popular superstition sometimes treated them that way. They were physical reminders of covenant obligations.
The practice grew from a plain-sense reading of texts like Exodus 13:9, which says, "It shall be for a sign to you on your hand, and for a memorial between your eyes, that Yahweh’s law may be in your mouth; for with a strong hand Yahweh has brought you out of Egypt." A faithful Israelite could take such language figuratively, as a call to let God's law govern action and attention, or literally, as an instruction to wear visible tokens. Both readings existed in Judaism. By Jesus' day the literal practice was well established, and it was not itself the target of his rebuke. Jesus himself likely wore fringes, since he kept the Law.
It helps to picture the physical object. The boxes were small, often less than two centimeters square, made of the hide of a clean animal, stitched with sinew, and dyed black. Inside, a trained scribe wrote the assigned passages in tiny, careful Hebrew letters on parchment prepared for sacred use. The arm box and head box were not identical in shape; the head box was divided into four compartments, one for each passage, while the arm box held a single scroll. Wearing them was a daily discipline, not a festival gesture, and it was tied to morning prayer. The details mattered to those who wore them.
This background matters because it shows how concrete the dispute in Matthew 23 really was. Jesus was not arguing about an abstract idea. He was standing in a culture where a specific, visible religious object could be seen by everyone at the synagogue and in the street. Enlarging that object was therefore a public statement. A man could not make his phylactery broad without other people noticing. The size of the box became a billboard, and that is precisely the dynamic Jesus named. The object was meant to point to God; the enlarged version pointed to the man wearing it.
The command behind the custom
The commands that gave rise to phylacteries appear in three places in the Torah. Deuteronomy 6:8-9 says, "You shall bind them for a sign on your hand, and they shall be for frontlets between your eyes." Exodus 13:16 says, "It shall be for a sign on your hand, and for symbols between your eyes; for by strength of hand Yahweh brought us out of Egypt." And Deuteronomy 11:18 says, "Therefore you shall lay up these words of mine in your heart and in your soul. You shall bind them for a sign on your hand, and they shall be for frontlets between your eyes." The repetition is deliberate. God wanted his words impossible to forget.
Notice the sequence in Deuteronomy 11:18. The command to lay up the words in heart and soul comes first, and the binding on hand and forehead follows. The inward reality is stated before the outward sign. That order is not accidental. The sign was always meant to express something already happening inside the person. If the heart was empty, the box on the forehead became a costume. This is the tension Jesus exposed centuries later. The sign can survive long after the reality it signified has died, and when that happens, the sign does active harm by lending credibility to a hollow life.
The word frontlets suggests something worn between the eyes, across the brow. The word sign suggests something visible that points beyond itself. Both words assume an observer and a meaning. A sign that no one could see would fail its purpose, so public visibility was built into the command from the start. This is important because it means Jesus was not condemning visibility as such. He was condemning visibility pursued for its own sake. The command wanted God's deliverance from Egypt remembered; the Pharisees wanted their own devotion admired. Same object, opposite direction.
Deuteronomy also ties the command to speech: the law was to be in the mouth. That means the visible sign and the spoken word belonged together. A man wearing a phylactery was supposed to be a man who talked about Yahweh's law naturally, at home, on the road, at night, in the morning. The box was a prompt for conversation and meditation, not a substitute for either. When the prompt becomes the whole religion, the wearer has replaced the message with the packaging. Jesus' criticism lands exactly there, on a sign detached from the speech and the heart it was meant to serve.
What Jesus actually criticized in Matthew 23:5
Matthew 23:5 reads, "But they do all their works to be seen by men. They make their phylacteries broad, enlarge the fringes of their garments." The first clause is the diagnosis and the second is the symptom. Jesus did not say the boxes were wrong. He said the works were done to be seen. That single phrase governs everything that follows in the chapter, including the seat of Moses, the greetings in the marketplace, and the titles people loved. The broad phylactery was one instance of a general pattern, and the pattern was audience-driven religion. The audience was not God.
The fringes mentioned alongside the phylacteries come from Numbers 15:38-39 and Deuteronomy 22:12, where Israel was told to make tassels on the corners of their garments so that they would remember the commandments and not follow their own hearts and eyes. Again the purpose was remembrance. Again the practice was legitimate. Again it could be inflated. Enlarging the fringe made the tassel more visible from a distance, which meant a man could be identified as especially devout before he ever opened his mouth. Jesus grouped the two customs because they shared the same corruption: a reminder turned into an advertisement.
It is worth sitting with the phrase to be seen by men, because it names a motive rather than an action. Two men can perform the identical act, and one can be righteous while the other is performing. The Pharisees were not accused of skipping prayer or ignoring Scripture. They were accused of doing real religious works for the wrong audience. That is a subtler and more searching charge than hypocrisy about facts. It means the danger is not confined to people who are obviously fake. Anyone who has ever felt a small pleasure at being noticed praying has touched the same edge.
Jesus also said they do all their works this way. The word all closes the escape hatch. It is not that most of their works were sincere and a few were showy. The pattern ran through everything, which is why he could pronounce woe after woe in the same chapter without pausing to praise a single exception. When the audience is human, the whole religious life bends toward display, even the parts that look private. The broad phylactery was simply the visible tip of an orientation that reached to the roots of the man.
Broad phylacteries as a status symbol
Why would anyone want a larger box? The obvious answer is that bigger is more noticeable. In a synagogue crowd, a man with an oversized phylactery and long fringes stood out. People would assume he was unusually serious about the Law. That assumption carried social weight: invitations, respect, the best seats, greetings in the marketplaces. Jesus names those rewards directly in Matthew 23:6-7, describing those who love the chief place at feasts and the chief seats in synagogues, and the greetings in the marketplaces, and to be called Rabbi by men. The enlarged box was the entry ticket to that economy.
This is a universal human pattern, not a first-century oddity. Every religious culture has its equivalent of the broad phylactery, some visible marker that signals devotion and earns standing. It might be a worn Bible, a prayer schedule mentioned in conversation, a vocabulary of piety, a position on a committee, or a carefully angled social media post. The marker itself may be good. The problem arrives when the marker becomes the point, when the wearer is managing an impression rather than seeking God. Jesus identified this in a specific object so that we could recognize it in our own objects.
There is also a competitive dimension. If one man widens his box, another can widen his further, and soon the standard creeps upward. Status symbols inflate because they are comparative. This is why Jesus' critique is not solved by making phylacteries smaller; it is solved by changing the audience. The moment the goal is to be seen, the size question becomes a race with no finish line. The Pharisees were not evil because they had boxes. They were trapped because their boxes were measuring sticks, and they were using them to measure themselves against everyone else in the room.
It is telling that Jesus did not respond by abolishing the customs. He did not tell the crowds to stop wearing fringes or to throw away their phylacteries. He told them to do what the scribes and Pharisees taught, but not to follow their example, because they did not practice what they preached. His remedy was not the removal of religious practice but the correction of its aim. That is a pastoral word for anyone tempted to solve pride by stripping away every external form. Removing the form does not remove the audience problem. A man can be just as proud of his plainness as of his ornament.
The wider pattern in Matthew 23
Matthew 23 is a sustained critique of religious performance, and the phylactery verse sits near the opening as a kind of thesis statement. What follows includes tithing mint and dill and cumin while neglecting the weightier matters of justice, mercy, and faith; cleansing the outside of the cup while the inside is full of greed; and whitewashed tombs that look beautiful outside but hold death within. Each image makes the same point in a different register. The outside is being managed; the inside is being ignored. The broad phylactery is the visual form of that same division.
The chapter also shows where performance leads. Jesus says the scribes and Pharisees sit on Moses' seat, so the crowds should observe and do what they say, but not do their works, because they say and do not do. He says they bind heavy burdens and lay them on men's shoulders but will not lift a finger to move them. Performance-based religion is not only self-serving; it is also crushing for the people watching. When leaders use visible devotion to secure their own standing, they inevitably make the standard higher for everyone else while offering no help to meet it.
There is an irony in the sequence that is easy to miss. The very practices meant to remind Israel of God's deliverance from Egypt became a means of self-exaltation in the house of God's people. The sign designed to say Yahweh brought us out became a sign saying look at me. That reversal is the deepest danger the passage warns about. It is not that religious objects are bad. It is that any object, however good, can be turned to serve the ego. The best reminders make the worst idols precisely because they are so close to the truth.
Jesus ends the chapter with a lament over Jerusalem, longing to gather her children under his wings. That ending keeps the whole critique from becoming mere sarcasm. He is not sneering at the Pharisees from a safe distance. He is grieving over a city that killed the prophets and now fails to recognize the one sent to her. The warning about broad phylacteries is therefore pastoral, not contemptuous. It is spoken by someone who wants people free from the exhausting work of managing a reputation before other people, and free for the rest of being known by God.
What this means for your own devotion
The practical question is not whether you own visible markers of faith. Most believers do. The question is who you are performing for when you use them. A simple test is what happens when no one notices. If you pray, give, read, or serve with equal freedom when there is no audience, the marker is probably serving its purpose. If the practice shrivels when the audience disappears, the audience was always the point. This is a matter for honest self-examination, not for anxious scrupulosity, and it is best done in the presence of God rather than in comparison with other people.
Jesus offers a different economy in the same Sermon on the Mount tradition. He tells his disciples to give, pray, and fast without announcing it, and he promises that the Father who sees in secret will reward. That does not mean secrecy is a rule to be enforced on everyone else. It means the Father's attention is enough. If God sees, the need for human recognition loses its grip. The broad phylactery was an attempt to secure an audience that could not see the heart. The Father already sees it, which makes the whole performance unnecessary.
It is worth being gentle with yourself here. Recognizing the desire to be seen is not the same as being free of it, and no one becomes indifferent to reputation overnight. The Pharisees were not monsters; they were men shaped by a culture of honor and shame who took the path of least resistance. Most of us would have done the same in their sandals. The point of Jesus' warning is to make us aware, not to make us despair. Awareness is where change begins, and God is patient with the slow work of reorienting a heart away from applause.
Finally, remember what the phylactery was for. It was a reminder that Yahweh brought his people out of Egypt with a strong hand. Every time a man strapped it on, he was supposed to recall rescue, not rehearse his own excellence. That is still the right use of every reminder we carry, whether a book, a symbol, a habit, or a rhythm of prayer. The gospel is not a story about how impressive we are. It is a story about what God did. Whatever helps you remember that is worth keeping, and whatever turns it into a mirror is worth examining.
Biblical fidelity check
What the passage does establish is this: Jesus rebuked the scribes and Pharisees for doing their works to be seen by men, and he named broad phylacteries and enlarged fringes as examples of that motive. What the passage does not establish is a prohibition on wearing phylacteries or fringes at all. Jesus did not say the objects were sinful, and he did not instruct his followers to discard them. Matthew 23:5 is a statement about the purpose behind the practice, not about the practice's legitimacy. Reading it as a blanket ban on religious externals goes beyond what the text says.
A common misreading treats this verse as proof that outward religious observance is inherently hypocritical, so the sincere believer should abandon all visible forms, symbols, and traditions. That misreading fails for several reasons. The same Law that commanded the fringes is affirmed by Jesus elsewhere, and he told the crowds to do what the scribes taught while rejecting their example. If externals were the problem, Jesus would have said so directly. The problem was the audience, and changing the audience does not require abolishing the sign. Where faithful Christians differ is on how much visible form is wise; Scripture leaves room for that discussion, and it is not the same question as the one Jesus answered here.
Other passages that speak to Matthew 23:5
Several studies on this site trace the same themes of covenant remembrance, heart obedience, and the danger of performance. Deuteronomy 1: Moses Rehearses Israel's Journey and Failure shows how remembering God's acts grounds Israel's identity. Deuteronomy 10: Renewed Tablets and Heart Circumcision presses the inward demand behind the outward sign. Deuteronomy 11: Love, Obey, Blessing and Curse contains the very commands about binding words on hand and forehead. And The Beatitudes Explained: Matthew 5:1–12 Meaning sets out the kingdom posture that stands in contrast to the religion of display Jesus exposes in Matthew 23.
Frequently asked questions
Did Jesus wear phylacteries?
Scripture does not say explicitly whether Jesus wore phylacteries. It does say he wore the fringes commanded in Numbers 15 and Deuteronomy 22, since the woman with the issue of blood touched the fringe of his garment. He lived as a faithful Jew under the Law, and he told the crowds to do what the scribes taught. So he was not opposed to the customs themselves. What he opposed was doing religious works to be seen by men. Whether he personally wore tefillin is not stated, and we should be careful not to assert more than the text gives us.
Are phylacteries the same as tefillin today?
Yes, phylactery is the Greek term used in Matthew 23:5, and tefillin is the later Hebrew name for the same practice. Observant Jewish men still wear them today, typically during weekday morning prayer. The contents remain the four Torah passages, and the placement on the arm and forehead follows the ancient pattern. The word phylactery carried a nuance of a safeguard or protective object, which is why some translations and teachers prefer tefillin to avoid the superstitious overtone that the Greek term could suggest.
Does Matthew 23:5 mean I should hide my faith?
No. Jesus also told his followers to let their light shine before others, and he expects public confession of him. The issue in Matthew 23:5 is motive, not visibility. Giving, praying, and fasting are not to be done for the purpose of being noticed, but that does not mean hiding that you belong to Christ. A believer can serve openly and still serve for God's approval rather than people's. The question to ask is whether the audience you are seeking is the Father who sees in secret, or the crowd whose attention fades by evening.
