Every Jew is requierd to recite the Sh'ma, twice a day in the morning and evening.
And as the fulfillment of the precept says ' When you lie down and when you rise up'
The Sh'ma is a essential part of the morning and evening prayer, but it is a declaration of faith, and a affirmation of G'D reminding us of the commitment to Him.
The morning and evening prayer include the fallowing passage
Shema yisrael, adonai eloheinu adonai echad. Baruch Shem kvod malchuto, l'olam va 'ed. V' a-havta et adonai elohecha b'col l'vavcha uv- chol naf- sh'cha uv-chol m' odecha. V' hayu hadvarim ha - aileh, asher anochi m- tzav-cha ha- yom, al l' vavecha. V' sheenantam l' vanecha, v'dee- barta bam b' sheev- t'cha b' vaitecha, uv- lech- t'cha va -derech, uv- shach- b'cha uv- kumecha. Uk- shartam l'ot al yadecha, v'hayu l' totafot bayn aynecha. Uch- tavtam al mezuzot baytecha u- vish- arecha.
Hear, O Israel, the Lord is our G'D, the Lord is One. Blessed be the name of his glorious Majesty forever and ever. Love the Lord your G'D with all your heart, with all your soul, with all your means. And these words which I command you today shall be upon your heart. Teach them diligently to your children, and talk of them when you sit in your house, when you walk on the road,when you lie down and when you rise up. Bind them for is a sign upon your hand and for frontlets between your eyes.Write them upon the doorposts of your houses and upon your gates.
