what is the purpose of a comma in a sentence
Comma The comma is used in many contexts and languages, mainly for separating parts of a sentence such as clauses, and items in lists, particularly when there are three or more items listed. The word comma comes from the Greek κόμμα (kómma), which originally meant a cut-off piece; specifically, in grammar, a short clause.[1][2]
Shema Yisrael Originally, the Shema consisted of only one verse: Deuteronomy 6:4 (see Talmud Sukkah 42a and Berachot 13b). The recitation of the Shema in the liturgy, however, consists of three portions: Deuteronomy 6:4–9, 11:13–21, and Numbers 15:37–41. The three portions are already mentioned in the Mishnah (Berachot 2:2). The three portions relate to central issues of Jewish belief. In the Mishnah (Berakhot 2:5) the reciting of the shema was linked with re-affirming a personal relationship with God's rule. Literally, reciting the shema was stated as "receiving the kingdom of heaven." ["Heaven" is a metaphor for God. The best texts of the Mishnah, Kaufmann and Parma, do not have the addition "yoke" that is found in later printed Mishnahs: "receive the {yoke of the} kingdom of Heaven." The original statement appears to have been "to receive the kingdom of Heaven".]
