King David in the context of "King asleep in mountain"

The Twelve Tribes of Israel (Hebrew: שִׁבְטֵי־יִשְׂרָאֵל, romanized: Šīḇṭēy Yīsrāʾēl, lit. 'Staffs of Israel') are described in the Hebrew Bible as being the descendants of Jacob, a Hebrew patriarch who was a son of Isaac and thereby a grandson of Abraham. Jacob, later known as Israel, had a total of twelve sons, from whom each tribe's ancestry and namesake is derived: Reuben, Simeon, Levi, Judah, Dan, Naphtali, Gad, Asher, Issachar, Zebulun, Joseph, and Benjamin. Collectively known as the Israelites, they inhabited a part of Canaan—the Land of Israel—during the Iron Age. Their history, society, culture, and politics feature heavily in the Abrahamic religions, especially Judaism.

In the biblical narrative, after Moses oversaw the Israelites' departure from Egypt, he died and was succeeded by Joshua, who led the conquest of Canaan and subsequently allotted territory for all but the Tribe of Levi, which was instead dedicated 48 cities. This development culminated in the establishment of Israel and Judah, purportedly beginning with a Kingdom of Israel and Judah before splitting into the Kingdom of Israel in the north and the Kingdom of Judah in the south.

The royal doors, holy doors, or beautiful gates are the central doors of the iconostasis in an Eastern Orthodox or Eastern Catholic church. The sanctuary (sometimes called the Altar, which contains the Holy Table) is separated from the nave by a wooden screen called the iconostasis. The iconostasis represents Christian continuity from the veil of the Temple in Jerusalem which separated the people from the Holy of Holies that housed the Ark of the Covenant. Normally, the iconostasis has three doors in it. The two single doors to the right and left are called "deacons' doors" or "angel doors" and they usually have on them icons of either sainted deacons (Saint Stephen, Saint Lawrence, etc.) or the Archangels Michael and Gabriel. These are the doors that the clergy will normally use when entering the sanctuary. The central double doors are the "holy doors" (Slavonic: Svyatýa Vratá), which are considered to be most sacred, and may only be entered at certain sacred moments during the services, and only by ordained clergy (deacons, priests, bishops).

The term Royal Doors (Greek: Ωραία Πύλη: Slavonic: Tsárskiya Vratá) is commonly used to describe the Holy Doors, because Christ passes through these gates during the Great Entrance at the Divine Liturgy (and most especially during the Liturgy of the Presanctified Gifts). More properly, however, these doors should be called the "Beautiful Gate", and in Greek this is the only term used, although the official English sites of the Ecumenical Patriarchate, the Orthodox Church in America and the Antiochian Orthodox Church all use the term "Royal Doors". In Russia, they are sometimes called the "Red Gates", red being synonymous with beautiful.

Khirbet Qeiyafa (Arabic: خِرْبَة قِيَافَة, romanized: Khirbat Qiyāfa), also known as Elah Fortress and in Hebrew as Horbat Qayafa (Hebrew: חוֹרְבָת קַייָאפַה), is the site of an ancient fortress city overlooking the Valley of Elah and dated to the first half of the 10th century BCE. The ruins of the fortress were uncovered in 2007, near the Israeli city of Beit Shemesh, 30 km (20 mi) from Jerusalem. It covers nearly 2.3 ha (6 acres) and is encircled by a 700-meter-long (2,300 ft) city wall constructed of field stones, some weighing up to eight tons. Excavations at site continued in subsequent years. A number of archaeologists, mainly the two excavators, Yosef Garfinkel and Saar Ganor, have claimed that it might be one of two biblical cities, either Sha'arayim, whose name they interpret as "Two Gates", because of the two gates discovered on the site, or Neta'im; and that the large structure at the center is an administrative building dating to the reign of King David, where he might have lodged at some point. This is based on their conclusions that the site dates to the early Iron IIA, ca. 1025–975 BCE, a range which includes the biblical date for the biblical Kingdom of David. Others suggest it might represent either a North Israelite, Philistine, or Canaanite fortress, a claim rejected by the archaeological team that excavated the site. The team's conclusion that Khirbet Qeiyafa was a fortress of King David has been criticised by some scholars. Garfinkel (2017) changed the chronology of Khirbet Qeiyafa to ca. 1000–975 BCE.

Goliath (/ɡə.ˈlaɪ.əθ/ gə-LY-əth) is a Philistine warrior of giant stature who plays a pivotal role in the origin myth of King David in the Book of Samuel. According to 1 Samuel, Goliath challenges the Israelites to best him in single combat. David, then a young shepherd, takes up the challenge and kills Goliath with a stone slung from a sling. The narrative signifies King Saul's unfitness to rule for not taking up the giant's challenge himself.

The phrase "David and Goliath" has taken on a more popular meaning denoting an underdog situation, a contest wherein a smaller, weaker opponent faces a much bigger, stronger adversary. Some modern scholars now believe that the original slayer of Goliath in the text may have been Elhanan, son of Jair, who features in 2 Samuel 21:19, in which Elhanan kills Goliath the Gittite, and that the authors of the Deuteronomistic history changed the original text to credit the victory to the more famous figure of David.

Gad (Hebrew: גָּד, Modern: Gad, Tiberian: Gāḏ, "luck", /ɡæd/) was a seer or prophet mentioned in the Hebrew Bible and the writings of Jewish historian Josephus. He was one of the personal prophets of King David of Israel and, according to the Talmudic tradition, some of his writings are believed to be included in the Books of Samuel. He is first mentioned in 1 Samuel 22:5 telling David to return from refuge in Moab to the forest of Hereth in the land of Judah.

The next biblical reference to Gad is 2 Samuel 24:11–13 (1 Chronicles 21:9–13) where, after David confesses his sin of taking a census of the people of Israel and Judah, God sends Gad to David to offer him a choice of three forms of punishment.

Knowledge of the biblical period is mostly from literary references in the Bible and post-biblical sources. Religion and music historian Herbert Lockyer, Jr. writes that "music, both vocal and instrumental, was well cultivated among the Hebrews, the New Testament Christians, and the Christian church through the centuries." He adds that "a look at the Old Testament reveals how God's ancient people were devoted to the study and practice of music, which holds a unique place in the historical and prophetic books, as well as the Psalter."

The music of religious ritual was first used by King David: according to the Larousse Encyclopedia of Music, he is credited with confirming the men of the Tribe of Levi as the "custodians of the music of the divine service". Historian Irene Hesk notes that of the thirty-nine books of the Old Testament, the 150 Psalms in the Book of Psalms, [many] ascribed to King David, have served as "the bedrock of Judeo-Christian hymnology," concluding that "no other poetry has been set to music more often in Western civilization."
