In the Bible, Zion is the eastern hill of Jerusalem which included the Temple Mount (Moriah) and the hill south of it (Ophel). The fortress on the hill south of the Temple Mount is named the stronghold of Zion (II Sam 5:7). The etymology of this name remains unexplained and may be of great antiquity. After David's conquest of the city, the stronghold of Zion was called the City of David (II Sam 5:7, 9; I Chr 11:7). Solomon brought up the ark of the covenant of the Lord "from the City of David, which is Zion" (I Kgs 8:1-2; II Chr 5:2). It then became the city of God, the city of the great king (Ps 46:4; 48:2); it is a holy hill (Ps 2:6; Joel 2:1; Zech 8:3); God dwells there (Ps 9:11; 132:13) and there is his sanctuary (Ps 20:2), which is a goal of pilgrimage (Ps 84:5, 7), a place of deliverance and salvation (Ps 20:1-2; 69:35), and of praise and worship (Ps 9:14; 65:1). When the ark was transferred to Mount Moriah, it came to be called Mount Zion (Ps 78:68-69).
The name Zion became synonymous with Jerusalem (Is chap. 40; Mic 3:12). The sons of Zion (Lam 4:2) and the daughters of Zion (Song 3:11; Is 10:32) denoted the inhabitants of Jerusalem (Jer 51:35). Zion is the whole city, which, like other fortified cities of Judah, was a place of safety; people of other cities will be brought to Zion (Jer 3:14; 4:5-6).
After the Exile the Israelite nation came to be called "Zion� who dwelt with the daughter of Babylon" (Zech 2:7). The "daughter of Zion" personifies the entire people (Jer 6:23; Zech 9:9), as do the "sons of Zion" (Zech 9:13). Divine protection makes the city – "the virgin (the) daughter of Zion" – pure (II Kgs 19:21; 37:22; cf Jer 14:17; 18:13; 31:4, 21; Lam 1:15; Amos 5:2). Since God himself founded Zion, the people may anticipate safety within its walls, because it is protected by God himself (Is 14:32; 31:8-9; 33:1-5). But should the people of Israel forsake God, he will smite the daughter of Zion (Is 3:17; 49:14; Jer 6:2ff; 9:19). The mere existence of the Temple on Mount Moriah is not a safeguard and reliance on it alone is equated with "lying words" (Jer 7:4, 8, 12); sin leads to the destruction of Zion (Jer 9:20).
There is little reference to Zion in the NT. It is named "the city of the living God, the heavenly Jerusalem" (Heb 12:22). The term refers to the people of Israel (Rom 9:33; I Pet 2:6), and of Jerusalem (Matt 21:5; John 12:15), and to the mountain upon which Jesus and his followers will stand in triumph on his Second Coming (Rev 14:1).
