What does Psalm 62:2 mean?

Ancient castles were made of stone, and modern bunkers are made of concrete and other rocky substances. Even in modern construction, a foundation of solid rock is the standard of security and stability. Jesus used this metaphor in one of His more well-known teachings (Luke 6:48). David's words in this verse highlight this theme of trust in the Lord as a perfect, unchanging, immovable foundation of faith. Rather than raging in anger or wailing in despair, David's faith in God allows him to be at peace (Psalm 62:1), expecting the Lord to act at the appropriate time (Psalm 62:5).

In Psalm 27:1 David writes, "The LORD is the stronghold of my life; of whom shall I be afraid?" Even when faced with physical danger, he was assured of the Lord's goodness (Psalm 27:3). Because God is with the believer every step of life's journey (Hebrews 13:5), the believer can confidently say, "The Lord is my helper; I will not fear; what can man do to me?" (Hebrews 13:6).

This sentiment is repeated almost identically later in this song (Psalm 62:6).
