Tetragrammaton in the context of "Kyrios"

Shema Yisrael (Shema Israel or Sh'ma Yisrael; Hebrew: שְׁמַע יִשְׂרָאֵל, lit. 'Hear, O Israel') is a Jewish prayer (known as the Shema) that serves as a centerpiece of the morning and evening Jewish prayer services. Its first verse, Deuteronomy 6:4, encapsulates the monotheistic essence of Judaism: "Hear, O Israel: YHWH our God, YHWH is one" (שְׁמַע יִשְׂרָאֵל יְהוָה אֱלֹהֵינוּ יְהוָה אֶחָֽד׃).

The first part can be translated as either "The LORD our God" or "The LORD is our God", and the second part as either "the LORD is one" or as "the one LORD" (in the sense of "the LORD alone"). Hebrew does not generally use a copula in the present tense, so translators must decide by inference which translation is appropriate in English. The word used for "the LORD" is the Tetragrammaton (YHWH).

In Judaism, God has been conceived in a variety of ways. Traditionally, Judaism holds that God—that is, the god of Abraham, Isaac and Jacob, and the national god of the Israelites—delivered them from slavery in Egypt, and gave them the Law of Moses at Mount Sinai as described in the Torah. Jews believe in a monotheistic conception of God ("God is one"), characterized by both transcendence (independence from, and separation from, the material universe) and immanence (active involvement in the material universe).

God is seen as unique and perfect, free from all faults, and is believed to be omnipotent, omnipresent, omniscient, and unlimited in all attributes, with no partner or equal, serving as the sole creator of everything in existence. In Judaism, God is never portrayed in any image. The names of God used most often in the Hebrew Bible are the un-pronounced Tetragrammaton (Hebrew: יהוה, romanized: YHWH) and Elohim. Other names used to refer to God in traditional Judaism include Adonai, El-Elyon, El Shaddai, and Shekhinah.

Elijah (/ɪˈlaɪ(d)ʒə/ ih-LEYE-jə or ih-LEYE-zhə) or Elias ("My God is Yahweh/YHWH") was a prophet and miracle worker who lived in the northern kingdom of Israel during the reign of King Ahab (9th century BC), according to the Books of Kings in the Hebrew Bible.

In 1 Kings 18, Elijah defended the worship of the Hebrew deity Yahweh over that of the Canaanite deity Baal. God also performed many miracles through Elijah, including resurrection, bringing fire down from the sky, and ascending to heaven alive. He is also portrayed as leading a school of prophets known as "the sons of the prophets". Following Elijah's ascension, his disciple and devoted assistant Elisha took over as leader of this school. The Book of Malachi prophesies Elijah's return "before the coming of the great and terrible day of the LORD", making him a harbinger of the Messiah and of the eschaton in various faiths that revere the Hebrew Bible. References to Elijah appear in Sirach, the New Testament, the Mishnah and Talmud, the Quran, the Book of Mormon, and Baháʼí writings. Scholars generally agree that a historical figure named Elijah existed in ancient Israel, though the biblical accounts of his life are considered more legendary and theologically reflective than historically accurate.

In Abrahamic religions, the Garden of Eden (Biblical Hebrew: גַּן־עֵדֶן‎, romanized: gan-ʿĒḏen; Greek: Εδέμ; Latin: Paradisus) or Garden of God (גַּן־יְהֹוֶה‎, gan-YHWH and גַן־אֱלֹהִים‎, gan-Elohim), also called the Terrestrial Paradise, is the biblical paradise described in Genesis 2–3 and Ezekiel 28 and 31.

The location of Eden is described in the Book of Genesis as the source of four tributaries. Various suggestions have been made for its location: at the head of the Persian Gulf, in southern Mesopotamia where the Tigris and Euphrates rivers run into the sea; and in Armenia. Others theorize that Eden was the entire Fertile Crescent or a region substantial in size in Mesopotamia, where its native inhabitants still exist in cities such as Telassar.

The Bible usually uses the name of God in the singular (e.g. Ex. 20:7 or Ps. 8:1), generally using the terms in a very general sense rather than referring to any special designation of God. However, general references to the name of God may branch to other special forms which express His multifaceted attributes. The Old Testament/Hebrew Bible reveals YHWH (often vocalized with vowels as "Yahweh" or "Adonai") as the personal name of God, along with certain titles including El Elyon and El Shaddai. Jah or Yah is an abbreviation of Jahweh/Yahweh, and often sees usage by Christians in the interjection "Hallelujah", meaning "Praise Yah", which is used to give God glory. In the New Testament the terms Theos, Kyrios and Patēr (πατήρ i.e. Father in Greek) are additionally used to reference God.

Respect for the name of God is one of the Ten Commandments, which some Christian teachings interpret to be not only a command to avoid the improper use of God's name, but a directive to exalt it through both pious deeds and praise. This is reflected in the first petition in the Lord's Prayer addressed to God the Father: "Hallowed be Thy Name".

Judaism has different names given to God, which are considered sacred: יהוה (YHWH), אֲדֹנָי (Adonai transl. my Lord[s]), אֵל (El transl. God), אֱלֹהִים (Elohim transl. Gods/Godhead), שַׁדַּי (Shaddai transl. Almighty), and צְבָאוֹת (Tzevaot transl. [Lord of] Hosts); some also include I Am that I Am. Early authorities considered other Hebrew names mere epithets or descriptions of God, and wrote that they and names in other languages may be written and erased freely. Some moderns advise special care even in these cases, and many Orthodox Jews have adopted the chumras of writing "G-d" instead of "God" in English or saying Ṭēt-Vav (טו, lit. '9-6') instead of Yōd-Hē (יה, '10-5', but also 'Jah') for the number fifteen or Ṭēt-Zayin (טז, '9-7') instead of Yōd-Vav (יו, '10-6') for the Hebrew number sixteen.

There are various names of God and many titles that refer to God, many of which enumerate the various qualities of a Supreme Being. The English word god (and its equivalent in other languages) is used by multiple religions as a noun to refer to different deities, or specifically to the Supreme Being, as denoted in English by the capitalized and uncapitalized terms God and god. Ancient cognate equivalents for the biblical Hebrew Elohim, one of the most common names of God in the Bible, include proto-Semitic El, biblical Aramaic Elah, and Arabic ilah. The personal or proper name for God in many of these languages may either be distinguished from such attributes, or homonymic. For example, in Judaism the tetragrammaton is sometimes related to the ancient Hebrew ehyeh ("I will be"). It is connected to the passage in Exodus 3:14 in which God gives his name as אֶהְיֶה אֲשֶׁר אֶהְיֶה (Ehyeh Asher Ehyeh), where the verb may be translated most basically as "I Am that I Am", "I shall be what I shall be", or "I shall be what I am". In the passage, YHWH, the personal name of God, is revealed directly to Moses.

Correlation between various theories and interpretation of the name of "the one God", used to signify a monotheistic or ultimate Supreme Being from which all other divine attributes derive, has been a subject of ecumenical discourse between Eastern and Western scholars for over two centuries. In Christian theology the word is considered a personal and a proper name of God. On the other hand, the names of God in a different tradition are sometimes referred to by symbols. The question whether divine names used by different religions are equivalent has been raised and analyzed.
