2 Sam 5:7

5:7 stronghold of Zion. This marks the first occurrence of “Zion” in the Bible and the only one in Samuel. The name originally designated a fortified mound located at the southern end of the Ophel ridge. Eventually the name came to be used in an extended sense for all of Jerusalem (2 Kin. 19:21; Is. 2:3) and even for the entire nation of Israel (Ps. 149:2; Is. 46:13). The name occurs frequently in Israel’s poetic and prophetic literature, where it is often presented as the place of God’s mighty acts of salvation and judgment (e.g., Ps. 14:7; Is. 4:4; Lam. 4:11).
