After securing the Tefillin Shel Yad (the arm Tefillin) onto the bicep, one wraps the strap around the forearm in a particular pattern. This wrapping is not merely aesthetic—it is deeply rooted in Halacha, custom, and Kabbalistic meaning. How many coils are required? In which direction should one wrap? And what happens if one is in a rush or interrupted? What Is the Source for Wrapping the Strap Around the Arm? The Torah says, "Ukeshartam le'ot al yadecha"—"You shall bind them as a sign on your arm." The word "ukeshartam" implies binding, not just placing. Therefore, it is not enough to put the Bayit of the Tefillin Shel Yad on the bicep—one must also wrap the strap around the forearm to fulfill the Misva of binding. This is part of the Tefillin ritual itself, and not an optional step. How Many Times Must the Strap Be Wrapped? According to Sephardic custom, the strap is wrapped eight times around the forearm—between the Bayit on the bicep and the wrist. These eight coils correspond to spiritual and symbolic concepts, including the eight days leading to Berit Milah and the transcendence beyond nature. This number is rooted in the Kabbalistic teachings of the Arizal, and accepted as standard practice by Maran, the Ben Ish Hai, and Hacham Ovadia Yosef. Ashkenazim, however, often wrap the strap seven times, based on different understandings of the required act of "binding." Both customs are valid, and each person should follow their community's tradition. Is the Wrapping a Requirement or Just a Custom? The act of wrapping is a requirement, based on the Torah's word "Ukeshartam." However, the specific number of wraps (e.g., seven or eight) is a matter of custom and not me'akev—it does not invalidate the Misva if one wraps fewer or more times. That said, one should not treat this lightly. The number eight (for Sephardim) or seven (for Ashkenazim) carries deep significance, and by following the traditional count, one aligns with the spiritual energy intended by our sages. If someone accidentally wrapped fewer or more times, or if one of the coils slipped, the Misva is still valid. But it is best to adjust it as soon as possible and aim to wrap correctly the next time. Which Direction Should the Strap Be Wrapped? For Sephardim, the strap is wrapped inward, meaning that the coils go from the outer edge of the arm toward the body, forming a clockwise spiral when looking down the arm. This direction is based on the writings of the Ben Ish Hai, Arizal, and is codified in Yalkut Yosef. It symbolizes drawing the sanctity of the Tefillin inward, binding it to the soul. Some Ashkenazic authorities permit wrapping outward (counter-clockwise), and many Chassidic groups follow that custom. Each person should continue with their family or communal minhag. What Happens If One Wrapped in the Wrong Direction? The direction of the wrapping is not essential to the validity of the Misva. If a person wrapped in the wrong direction—out of habit, error, or imitation—the Tefillin are still kosher, and the blessing does not need to be repeated. However, one should try to correct the practice moving forward, especially if one has been educated or reminded of the proper custom for their community. Is There a Problem with Gaps or Overlaps in the Coils? Ideally, the wraps should be evenly spaced, firm but not tight, and placed one under the other in descending order. Overlapping or very loose coils are discouraged but do not invalidate the Misva. If one is rushed, or if the strap is very long or short, one may wrap looser or more tightly as needed. The main thing is to ensure that the strap forms clear, distinct coils down the forearm. Can the Strap Be Wrapped Over Clothing or a Watch? No. The strap must be wrapped directly on the skin of the forearm. Wrapping over a sleeve, wristwatch, or bandage creates a Hatssitsa (barrier), which may invalidate the Misva. Before wrapping, one should remove any watch or bracelet and ensure the skin is clean. If a person has a wound or bandage and cannot wrap fully, they should wrap to the extent possible on uncovered skin. When Is the Wrapping Performed in the Tefillin Sequence? After placing the Tefillin Shel Yad on the bicep and tightening it, the person recites the Beracha of "Le'hani'ah Tefillin." Then, without interruption, the strap is wrapped around the forearm. The wrapping around the fingers and hand comes after the Tefillin Shel Rosh is placed and secured. This later wrapping is more symbolic and poetic, reflecting verses of commitment to Hashem. But the forearm wrapping is part of the main Misva, and must be done immediately after the Beracha, without speaking or delay. Summary - Wrapping the strap around the forearm is part of the Torah commandment to "bind" Tefillin. - Sephardim wrap eight times; Ashkenazim often wrap seven. - The specific number and direction are not me'akev, but follow strong custom. - Sephardim wrap inward (clockwise), toward the body. - Coils should be neat and on bare skin, not over clothing or watches. - The wrapping must follow the Beracha, without delay or interruption.
