Shema Yisrael (“Hear, O Israel”) are the first two words of a section of the Torah that is the centerpiece of the morning and evening prayer services, encapsulating the monotheistic essence of Judaism:
“Hear, O Israel: G‑d is our L‑rd, G‑d is one.”
In its entirety, the Shema consists of three paragraphs: Deuteronomy 6:4–9, Deuteronomy 11:13–21 and Numbers 15:37–41.
Its recitation twice daily (morning and evening) is a biblical commandment. In addition, we recite it just before retiring for the night, as well as in the Kedushah service on Shabbat.
Indeed, this succinct statement has become so central to the Jewish people that it is the climax of the final Ne’ilah prayer of Yom Kippur, and is traditionally a Jew’s last words on earth.
