What does Psalm 121:3 mean?

There is a change in "voice" between verses 2 and 3 (Psalm 121:1–2). It seems the rest of the psalm records a response to the first two verses. The psalm might begin with the leader of a traveling group speaking and end with the group, or an individual in the group, responding.

The affirmation we see in verse 3 agrees with the first speaker's claim that the Lord, the Creator, helps him. References to paths, footing, and related terms are common in the Bible as symbols for safety and following God's will (Psalm 1:1; 17:5; 73:2; 119:105; Jude 1:24). In this context, the declaration is especially appropriate. A traveler through the hills might easily slip or slide on the rocky trail and be injured. In both a spiritual and physical sense, this verse encourages confidence in God's protection. Even when earthly hardships occur (Psalm 22:12–18; 25:16) we can know God is in control (Romans 8:37–39).

The travelers also make a point of declaring that the Lord is never caught unaware. First Peter 3:12 assures us that "the eyes of the Lord are on the righteous, and his ears are open to their prayer." As we journey through life as pilgrims, we can count on the Lord to watch over us. No struggle comes to us without His awareness or outside of His control (John 16:33).
