💬 הַפְטָרָה לְחַג הַפַּאי | Haftarah for the Festival of π (I Kings 7:23-26 and 8:54-66), the twenty-second day of the seventh month (which falls on Shemini Atseret)

Shmini Atseret is a strange festival. In some ways part of Sukkot, in some ways its own thing, it occupies an equivocal place in the yearly cycle. But one thing that is completely true: Shmini Atseret is on Pi Day. Well, Pi Approximation Day — the twenty-second day of the seventh month. Inspired by my friend and math enthusiast Aryeh Baruch (may he have a long life), I’ve compiled this altered form of the haftarah for Shmini Atseret in the diaspora, including the description of King Solomon’s “molten sea,” as well as an Aramaic “reshut” poem with a numeral acrostic of the first few digits of pi. . . .

יוֺם פּײַ | On the Rabbinical Approximation of π, by Boaz Tsaban and David Garber (1998)

There is a Rabbinical tradition that the value of pi is hidden within a ktiv-kri (reading-versus-writing disparity) in I Kings 7:23. According to Hebrew scriptural tradition, the word meaning ‘line’ is written as קוה, but read as קו. . . .

The views expressed on this page and in these shared works represents the views of their creator(s) and do not necessarily represent the views of the Open Siddur Project's developers, its diverse community of volunteer contributors, or its institutional partners.
We strongly advise against printing sacred texts and art containing divine names as these copies must be regarded with reverence, complicating their casual treatment and disposal.
If you must dispose of a printed sacred text (one containing Divine Names), please locate the closest genizah (often established by a synagogue) and contact its custodians for further instructions. We also recommend using Morah Yehudis Fishman's Prayer for Adding a Work to the Genizah.

Support this work: The Open Siddur Project is a volunteer-driven, non-profit, non-commercial, non-denominational, non-prescriptive, gratis & libre Open Access archive of contemplative praxes, liturgical readings, and Jewish prayer literature (historic and contemporary, familiar and obscure) composed in every era, region, and language Jews have ever prayed. Our goal is to provide a platform for sharing open-source resources, tools, and content for individuals and communities crafting their own prayerbook (siddur). Through this we hope to empower personal autonomy, preserve customs, and foster creativity in religious culture.
