Shema Yisrael

The Shema draws its opening line from Deuteronomy and is traditionally recited together with two following paragraphs, one commanding love of God with all one's heart, soul and might and teaching these words diligently to one's children, and a second, from Numbers, concerning the practice of wearing fringes, tzitzit. Jewish tradition does not describe the Shema as a creed in the sense familiar from Christian theology, since Judaism has generally resisted fixed dogmatic formulas of that kind, yet its declaration of God's oneness functions in practice as the closest thing Judaism has to a single required statement of belief, recited twice daily by observant Jews without exception.

Rabbinic law developed detailed rules about its recitation, including the specific time windows in the morning and evening during which it must be said and the requirement, where possible, to say it with a minyan, though unlike many other prayers it may also be recited alone. Its role at the deathbed, as the last words a dying Jew is traditionally encouraged to speak, gives the declaration of divine oneship a significance that extends well beyond its place in the ordinary daily liturgy. Talmudic discussion also debates precisely how much concentration, kavanah, is required for the first verse to count as validly recited, with some authorities holding that intention on the single opening line suffices even if attention lapses during the paragraphs that follow it.

The Shema's instruction to bind these words as a sign on the hand and between the eyes is read literally in traditional Jewish practice as the basis for tefillin, small leather boxes containing scriptural passages including the Shema, worn on the arm and head by observant adult Jews during weekday morning prayer. The same passage's command to write these words on the doorposts of the house underlies the mezuzah, a small case containing a handwritten parchment with the Shema text, affixed to doorframes in Jewish homes and touched or kissed by many as they pass through.

Because the Shema functions as a declaration rather than a request, it is recited standing still with a particular focus of attention, traditionally with the eyes covered by the hand while saying the first verse, a physical gesture meant to exclude distraction at the moment of affirming God's unity. Its recitation twice daily, in the morning and evening services, gives it a structural role in Jewish liturgy distinct from prayers reserved for a single service or occasion, closer in that respect to a fixed daily obligation than to devotional prayer offered as needed. Reform and other liberal Jewish movements have in some cases modified traditional practices surrounding tefillin and mezuzah observance, while continuing to treat the Shema itself as central liturgy, illustrating how the declaration's theological weight has remained stable even where associated ritual practice has varied across modern denominations.
