The Sh'ma is a traditional Jewish prayer that in English is translated to, "Hear, O Israel, the Lord Our God, the Lord is One." It professes the central tenet of Jewish faith: there is only one god. This belief is what differentiated the Judaism from all of the other polytheistic religions in the days of old. Furthermore, it continues to differentiate Judaism from Christianity by stressing that there is only one god and as opposed to the three-in-one idea held by many Christian sects.

The Sh'ma is very widely used, and occasions upon which it is said include during prayer and at death.
