What does Psalm 125:2 mean?

Jerusalem's mountains provided natural security. The city itself was founded when David captured a mountain stronghold (2 Samuel 5:7; 1 Kings 1:8). Mentions of Mount Zion (Psalm 2:6; 76:2; Jeremiah 51:24) are typically a reference to the city of Jerusalem. God's protection over the city rests on His people much more so than on the hills and buildings. At times, Jerusalem was virtually destroyed (2 Chronicles 36:17–21). Yet the Lord kept Israel from being absorbed and eventually brought them back (Ezra 2:1). This psalm celebrates the divine strength which keeps His people alive and protects them from falling into the sins of an evil culture (Psalm 125:1, 4–5).

A famous illustration of the Lord's supernatural protection is recorded in 2 Kings chapter 6. The prophet Elisha and his servant were surrounded by enemy Syrian forces in Dothan (2 Kings 6:15). Yet Elisha claimed that the enemy was outnumbered (2 Kings 6:16). After Elisha prayed on his behalf, a doubting servant was given the ability to see the massive army of fiery horses and chariots (2 Kings 6:17). Elisha eventually brought the entire horde to Samaria as virtual captives (2 Kings 6:18–23).
