The fact that God is one and has no equal is a belief that all Jews must believe. In Judaism, the sentence expressing this belief and the sentence that comes after it and mentions the love of God are mentioned in the Torah and are known as Shema. Essentially, the Shema consists of three texts in various parts of the Torah. Jewish clergy recognized the connection between these three texts and brought them together. Thus, the Shema, which gained a wholeness, gained a distinctive character of its own. In this study, the most important sentence of the Shema, which also reflects the title of the study, is Deuteronomy 6/4 (Listen, O Israel! The Lord our God is the only Lord) and Deuteronomy 6/5 (you will love the Lord our God with all your heart, with all your soul, with your strength) is emphasized. Texts other than these are excluded from the scope of the study. As a result of some discussions, the Shema was created by bringing together the relevant texts towards the end of the 2nd century and has been said as a whole until today. Shema reading is the holiest and most important practice in Jewish life. Because the Shema is considered the essence of the Jewish creed. The Shema is a confession of the Jewish faith more than a prayer. According to Jewish belief, the Shema refers to the dialogue between God and the Jews on Mount Sinai. In this context, the Shema is the call of God and the response of the Jews to that call. Schema is also a political discourse for Jews. It is said that the Jews never let the Shema down their tongues until their last breath. As a matter of fact, it is pointed out that even if all traces of Jewish identity are lost, Shema will retain its place in Jewish memory. As a matter of fact, Jews taught their children Shema even under the most difficult conditions. On the other hand, it is also known that Shema was used to provide moral support to Jewish patients. It is accepted that the first words of Shema have a protective power as well as a healing quality. The Word “Listen” in the first sentence of the Shema (Listen, O Israel! The Lord our God is the only Lord) refers to obedient listening. Listening also means listening carefully and thinking about the subject, understanding and comprehending. Because the listener not only hears the words of the speaker, but also becomes aware of the deep meanings underlying those words. The word "Israel" in the Shema refers to the entire Jewish nation that Moses called to "hear the unity of God." The first sentence of the Shema also clearly expresses the monotheistic belief in Judaism: "God is one". In Jewish thought, monotheism means that there is no god but Yahweh. The following second sentence of the Shema (Deuteronomy 6/5) is also frequently repeated: “You shall love the Lord our God with all your heart, with all your soul, with all your strength.” This statement emphasizes that a Jew should not only seek God's good pleasure, but also develop a loving relationship with God. According to Jewish belief, loving God is an act of worship. Recognition of God's oneness necessitates love of God. According to the generally accepted view, the love meant here should be a concrete love, not an abstract one. Concrete love, on the other hand, should be a concrete sign of fidelity, such as "obedience to God's law". On the other hand, the phrase you will love God “with all your heart” refers to all the passions of a Jew, including cognitive as well as emotional. In addition, with the command "You shall love God with all your might", Jews are asked to love God enough to sacrifice their possessions for God. However, the extent of the sacrifice to be made is a matter of debate. According to the most extreme view expressed in this regard, Jews are asked to give up all their material possessions for their faith and love for God. [ABSTRACT FROM AUTHOR]
